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. In most laser applications, the UC-2000’s
default PWM signal frequency of 5 kHz has proven to work well. When considering PWM frequencies at 5
kHz or below, please review Marking/engraving operation later in this chapter.
For high-speed motion applications that cannot tolerate any ripple in the optical beam response but still
need adjustable power levels, we recommend the use of higher PWM frequencies, up to 20 kHz maximum.
At 20 kHz, the laser’s optical beam response no longer follows the PWM input and is very nearly a DC
value with just a small amount of ripple present.
