All optical elements are aligned and locked into place by factory technicians before the laser is shipped. The structure of the resonator and internal beam conditioning optics combine to produce a near Gaussian mode quality (M2 factor) of <1.2.

  • Page 35: Figure 4-3 Converting 45° Linear Polarization To Circular Polarization

    LASER DESIGN PAGE Beam conditioning The p400 laser incorporates a novel beam conditioning system that first converts the beam to a circular profile, cleans up the beam to remove side lobes and improve beam quality. To do this, the laser beam exits the resonator and is turned back on itself through a front folding block that directs the beam into a cylindrical lens.

  • Page 37: Rf Power Supply

    RF POWER SUPPLY PAGE Table 4-1 Assist gas purity specifications. RF power supply P400 lasers are driven by four compact RF modules mounted internally in the laser chassis. Each RF module converts 48 VDC input power into a radio frequency (RF) signal that is then amplified and routed to its corresponding electrode structure in the laser tube where it excites the gas mixture in the tube to produce lasing.
  • Page 38 CONTROL SIGNALS PAGE Tickle pulse Tickle pulses pre-ionize the laser gas to just below the lasing threshold so that a further in-crease in pulse width adds enough energy to the plasma to cause laser emission. Tickle pulses cause the laser to respond predictably and almost instantaneously to PWM Command signals, even when there is considerable delay (laser off time) between applied Command signals.

  • Page 39: Figure 4-4 Pwm Command Signal Wave Form (Above) And Quasai Continuous Wave (Qcw) Explanation (Below)

    CONTROL SIGNALS PAGE Pulse frequency, the second parameter, is the repetition rate of the PWM input signal. The pulse frequency can range from a single shot up to a maximum frequency of 100 kHz. The third Command signal parameter, PWM duty cycle, is the percentage of the period that the Command signal is high.

  • Page 40: Figure 4-5 Typical Power Curve

    CONTROL SIGNALS PAGE Figure 4-5 Typical power curve. Important Note: Because the p400 is a pulsed laser, it will not operate when a constant 5V (100% duty cycle) PWM signal is applied. If this occurs, lasing will halt, and status LEDs/outputs will indicate a fault condition (see Troubleshooting in the Maintenance/Troubleshooting chapter for further information).

    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! 2. Visually inspect all optical surfaces in the beam path for contaminants. 3.

  • Page 88: Troubleshooting

    This section is designed to help isolate problems to the module level only. Problems on circuit boards or the laser tube are outside the scope of this guide because they are not user-serviceable assemblies; do not attempt to repair them. Contact NOVANTA or a NOVANTA Authorized Distributor for repair information.

  • Page 91 STATUS LED’S PAGE P400 LED indicators, also mirrored as output signals on the User I/O connector, provide status information to the user. Table below shows p400 output signal and LED indicator states during normal and fault conditions. User I/O outputs are Closed when the state indicated by the signal name is logically True.

When a Shutter Open Request signal is applied to the laser, PWM Command signals are inhibited until the shutter is fully open.

If a RF Drive Switch fault occurs, the laser requires service-Contact Contact NOVANTA Customer Service or a NOVANTA Authorized Distributor.

    Apply a PWM Command signal (at < 5% duty cycle) until the fault clears—typically less than 30 seconds. With either method, when breakdown does occur, lasing will begin immediately at the commanded PWM parameters without cycling DC power. If the No-Strike condition persists, contact NOVANTA or a NOVANTA Authorized Distributor.

  • Page 95: Frequency Limit Fault

    FREQUENCY LIMIT FAULT PAGE Frequency Limit fault Possible Causes: • The 100 kHz PWM frequency limit has been exceeded. Lasing is disabled when the input frequency limit is exceeded. When the input drops below 100 kHz, the laser will begin lasing immediately at the commanded PWM parameters without cycling DC Power. Duty Cycle/Pulse Width Limit fault Possible Causes: •...

    DUTY CYCLE/PULSE WIDTH LIMIT FAULT PAGE Symptom: • The p400 is connected to a network; however, the p400 web interface does not open or locks up while receiving data from the laser. Possible Causes: • The p400 laser was connected to the network using a crossover cable. A straight-through cable is required if connecting an p400 to a network via a network router, switch, or hub.

Warning: Serious Personal Injury Ensure that DC power to the laser is turned off and locked out before inspecting optical components in the beam path. Invisible CO2 laser radiation is emitted through the aperture.
