  • Page 27: Technical Reference Summary

    TECHNICAL REFERENCE SUMMARY PAGE Technical Reference Summary This section is a technical reference for your 32-1 laser and contains the following information: • Technical overview – briefly describes 32-1 technology, design RF power supply and basic optical setup. • Control circuitry & cooling – introduces various aspects of the 32-1 control signals & cooling.

  • Page 28: Introduction

    INTRODUCTION PAGE Introduction 32-1 lasers incorporate the latest technology in sealed carbon dioxide devices, combining the best features of both waveguide and free space CO2 laser technology. The all-metal laser tube construction features the ruggedness, stable optical support, and small size of waveguide lasers. Low cost is achieved by using simple extruded and welded aluminum structures packaged together with compact, state-of-the-art RF power supplies.
  • Page 29 PLASMA SECTION PAGE 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 30: Optical Setup

    OPTICAL SETUP PAGE Caution: Possible Equipment Damage Since 32-1 lasers are OEM products, they do not include cooling fans. Customers must provide some type of air cooling to prevent the laser from overheating. See the cooling requirements at the end of this chapter and cooling 101 located on our website.
  • Page 31 OPTICAL SETUP PAGE The chosen focal length should create the smallest possible focused spot while providing the depth of field required for the material to be processed. Optics are fragile and must be handled carefully, preferably by the mounting ring only. Be careful to select optics that are thick enough to withstand the maximum assist gas pressure available for the process.

  • Page 32: Control Signals

    • Operating modes Much of the information provided in this section describes the use of a NOVANTA® UC-2000 Universal Laser Controller to provide tickle and PWM signals to the laser. If you are using an alternate method of laser control, thoroughly review this section for an understanding of the signal requirements necessary to control NOVANTA 32-1 lasers.

  • Page 33: Figure 4-3 Tickle Pulse Waveform

    CONTROL SIGNALS PAGE The UC-2000 does not produce tickle pulses continuously but generates them only when the PWM signal is low. Tickle pulses are sent one tickle period, 200 μs, after the falling edge of a PWM signal pulse. Figure below illustrates tickle pulse parameters.

  • Page 34: Figure 4-4 32-1-2 Khz Waveform. The Upper Waveform Is Laser Output, The Lower Wave Form Is Pwm Input

    CONTROL SIGNALS PAGE 2 kHz Modulation Figure 4-4 32-1-2 kHz waveform. The upper waveform is laser output, the lower wave form is PWM input.

  • Page 35: Figure 4-5 32-1-5 Khz Waveform. The Upper Waveform Is Laser Output, The Lower Wave Form Is Pwm Input

    CONTROL SIGNALS PAGE 5 kHz Modulation Figure 4-5 32-1-5 kHz waveform. The upper waveform is laser output, the lower wave form is PWM input. 32-1 lasers are designed to operate at PWM signal base frequencies up to 20 kHz; however, the choice of PWM frequency depends on the user’s specific application.

  • Page 36: Figure 4-6 Pwm Signal Waveform

    PAGE Warning: Serious Personal Injury Always use shielded cable when connecting your PWM signal source to the laser’s PWM connections. In electrically noisy environments, long lengths of unshielded wire act like an antenna and may generate enough voltage to trigger un-commanded lasing. PWM signal The modulated PWM signal applied to 32-1 lasers has three parameters: signal amplitude, base frequency, and PWM duty cycle.

  • Page 37: Operating Modes

    Operating modes External control In addition to controlling your 32-1 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 38: Continuous Wave (Cw) Operation

    ±50 VDC from chassis ground. The 32-1 laser has one PWM input that should always be driven identically from the signal source by using a “Y” cable.

  • Page 39: Db-9 Connections

    DB-9 CONNECTIONS PAGE Warning: Serious Personal Injury The UC-2000’s default gate logic is factory set to internal Pull-Up (normally on) mode so that an open (disconnected) Gate input causes the laser to turn on. This functionality allows the user to easily test and verify laser operation prior to integration.

  • Page 44: Integrating 32-1 Safety Features

    • Remote Keyswitch functions The 32-1 DB-9 Connector allows system integrators or end-users to integrate 32-1 laser safety features into their control system. In particular, the 32-1 Remote Keyswitch function serves to disable DC power to the laser’s RF driver. Without power, the RF driver cannot supply PWM or tickle signals to the resonator, causing the CO2 gas to remain in a zero-energy state.
