  • Page 37: Introduction

    INTRODUCTION PAGE Introduction Series 48 lasers incorporate the latest technology in sealed carbon dioxide devices, combining the best features of both waveguide and free space CO laser technology. The all-metal laser tube construction features the ruggedness, stable optical support, and small size of waveguide lasers. Its larger bore (4.8 mm) eliminates the high optical power density of waveguide lasers with their predisposition to optical degradation and incorporates the mode purity and easy optical alignment of free space TEM00 lasers.

  • Page 38: Controlling Laser Power

    CONTROLLING LASER POWER PAGE Controlling Laser Power Electrical description Control of laser operation and power output levels is essentially performed using a single PCB. The Control PCB connects the modulated signal to the RF amplifier. It also provides electronics to monitor performance of RF control, output circuitry, input power, temperature, PWM accuracy, provides outputs to an externally accessible connector, and incorporates reverse polarity protection.

  • Page 39: Cooling

    COOLING PAGE (closed circuit). Power-On Reset is defeated on all OEM versions. OEM customers must provide this required safety feature elsewhere as part of their equipment integration. Cooling Series 48 electronics are mounted opposite the laser tube in the smaller section of the “H” bay and share the same cooling removal as the plasma tube.

The table above provides dew point temperatures for a range of air temperature and relative humidity values.

  • Page 42: Duo-Lase® Operation (48-5)

    DUO-LASE® OPERATION (48-5) PAGE Duo-Lase® operation (48-5) The 48-5 laser combines two laser tubes for twice the output of a standard laser. The outputs from two 25 W sealed CO2 tubes are combined optically to provide a single diffraction-limited beam at 50 W. This optical combining technique is based on the fact that each laser is linearly polarized, allowing the use of a polarization sensitive beam combiner to achieve 98% efficiency in combining the two beams.

  • Page 45: Figure 4-3 Tickle Pulse Waveform

    CONTROL SIGNALS PAGE Tickle pulse Series 48 lasers require a 1 μs tickle pulse delivered at a nominal 5 kHz clock frequency from the Controller. Tickle pulses pre-ionize the laser gas to just below the lasing threshold so that any further increase in pulse width adds enough energy to the plasma to cause laser emission.

  • Page 46: Figure 4-4 Series 48-2 Khz Waveform. The Upper Waveform Is Laser Output, The Lower Wave Form Is Pwm Input

    CONTROL SIGNALS PAGE Pulse width modulation (PWM) Pulse Width Modulation, or PWM, controls laser power by varying the duty cycle of the laser’s RF amplifiers, which in turn control the time-averaged RF power applied to the laser. Because laser output follows PWM input with a rise and fall time constant of ~100 μs, the laser cannot precisely follow Command signal frequencies over 5 kHz with duty cycles greater than 50%.

  • Page 47: Figure 4-5 Series 48-5 Khz Waveform. The Upper Waveform Is Laser Output, The Lower Wave Form Is Pwm Input

    CONTROL SIGNALS PAGE Figure 4-5 Series 48-5 kHz waveform. The upper waveform is laser output, the lower wave form is PWM input. Series 48 lasers are designed to operate at Command signal base frequencies up to 20 kHz; however, the choice of PWM frequency depends on the user’s specific application.

  • Page 48: Figure 4-6 Pwm Command Signal Waveform

    CONTROL SIGNALS PAGE Warning: Serious Personal Injury Always use shielded cable when connecting your PWM Command signal source to PWM Input / PWM Return inputs. In electrically noisy environments, long lengths of unshielded wire act like an antenna and may generate enough voltage to trigger uncommanded lasing. Command signal The modulated Command signal applied to Series 48 lasers has three parameters: signal amplitude, base frequency, and PWM duty cycle.

  • Page 49: Operating Modes

    OPERATING MODES PAGE Operating modes External control In addition to controlling your Series 48 laser using a UC-2000 Controller, controlling the laser externally, without a UC-2000, is also possible. The two primary elements of laser control are gating, the ability to turn the laser on and off at the appropriate times, and power, the ability to control the laser’s output energy.

  • Page 50: Continuous Wave (Cw) Operation

    CONTINUOUS WAVE (CW) OPERATION PAGE Continuous wave (CW) operation In some applications, such as high-speed marking or cutting, the time constant of the laser and the PWM modulation causes a series of dots that may be visible on the marking surface instead of a “clean” line. Operating the laser in CW mode will prevent this behavior from occurring.

  • Page 51: Db-9 Connections

    DB-9 CONNECTIONS PAGE Caution: Possible Equipment Damage Do not ground Remote Keyswitch or Remote Interlock inputs to an external circuit—this will damage laser circuitry. Any external circuit(s) connected to these terminals must be floating with respect to ground. We recommend using “dry circuit” (zero voltage) switches or relay circuitry. Do not apply a voltage to the Remote Interlock Input on DB-9 Connector Pin 3 as this will damage internal laser circuitry.

  • Page 52: Figure 4-7 Factory-Installed Db-9 Jumper Plug Wiring

    DB-9 CONNECTIONS PAGE Important Note: On lasers manufactured as OEM (-S) version lasers, i.e., without a Key switch, the Remote Interlock function is bypassed internally; however, the Remote Keyswitch function on Pin 6 and Pin 7 provides a similar functionality. Figure 4-7 Factory-installed DB-9 jumper plug wiring.

    INTEGRATING SERIES 48 SAFETY FEATURES PAGE Integrating Series 48 safety features • The Integrating Series 48 safety features section includes subsections: • Remote Keyswitch functions • Remote interlock functions The Series 48 DB-9 Connector allows system integrators or end-users to integrate Series 48 laser safety features into their control system.

  • Page 59: Remote Interlock Functions

    REMOTE INTERLOCK FUNCTIONS PAGE lasing is possible after the five-second delay. The output is inactive (PWR LED off) when lasing is disabled. Refer back to Table 3-6, DB-9 pin assignments for specific details. Remote interlock functions Keyswitch lasers Interlock circuits are often used to disable machinery when a shield, panel, or door is opened. The Series 48 remote interlock connects directly into an external, zero-voltage remote interlock circuit to prevent lasing by removing DC power from the laser’s RF driver boards when the circuit is electrically “open”.

  • Page 60: Water-Cooled Connections

    WATER-COOLED CONNECTIONS PAGE Water-cooled connections Setting coolant temperature Choosing the correct coolant temperature is important to the proper operation and longevity of your laser. When coolant temperature is lower than the dew point (the temperature at which moisture condenses out of the surrounding air), condensation forms inside the laser housing leading to failure of laser electronics as well as damage to optical surfaces.
  • Page 61 WATER-COOLED CONNECTIONS PAGE If your integrated laser application uses metric cooling tubing, we recommend the installation of tubing adaptors to convert 48-1/48-2 cooling kit fittings from 1/4” tubing to 6 mm metric tubing. For 48-5 cooling kits, convert the 3/8” tubing to 8 mm metric tubing. These tubing adaptors are available from many tubing and fitting manufacturers.

    CLEANING GUIDELINES PAGE the Dew Point temperature in °F (or °C). The chiller’s temperature setpoint must be set above the dew point temperature. For example, if the air temperature is 85 °F (29 °C) and the relative humidity is 60%, then the dew point temperature is 70 °F (21 °C).

  • Page 79: Cleaning Optics

    CLEANING OPTICS PAGE Cleaning optics Shut off and lock out all power to the laser. You must verify that the laser is OFF (in a zero-energy state) before continuing with the optical inspection! Visually inspect all optical surfaces in the beam path for contaminants. Remove loose contaminants from the optic by holding a clean air bulb at an angle to the optic and blow a stream of air at a glancing angle across the lens surface.
