    The optical resonator, in conjunction with the electrodes and the gas mixture, generates the laser beam. vi30/40 optical resonators are comprised of four optical elements: a rear mirror, two turning mirrors, and an output window. These optical elements are fastened to the tube’s exterior and are exposed to its interior through holes in the end caps.

  • Page 40: Operating Modes

    PWM input signals if the “On” pulse is less than 100 μs in duration. At a constant 50% duty cycle, vi30/40 lasers typically reach 90–100% of full optical output when operated at a frequency of 5 kHz and reach 65–80% optical output at 7 kHz. The percentage of optical output increases as duty cycle increases (at a constant PWM frequency) or as PWM frequency decreases (at a constant duty cycle).

  • Page 43 The vi30/40’s DB-9 I/O PWM input consists of a high-speed optoisolator LED with a forward voltage drop (Vf) of 1.5 VDC. The PWM input frequency can range from DC (0 Hz) to 100 kHz. The prior PWM command signal level table provides minimum, maximum, and nominal PWM signal specifications.
  • Page 44 OPERATING MODES PAGE Continuous wave (CW) 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.

    User outputs indicate vi30/40 ready, lase, overtempt, and input voltage status. The OEM vi30/40’s PWM inputs are optoisolated; however, all other inputs and outputs operate using standard 5V logic levels (0V – logic low; 5V – logic high). Both inputs and outputs are ESD protected but are not optoisolated;...
