PDM+: PULSE-ON-DEMAND MODULES
The PDM series consists of laser modules which generate optical pulses from input TTL/LVTTL digital signal.
From single-shot to CW, with pulse length from 1ns to any required pulse-burst configuration, the PDM series offers the best temporal flexibilty on the laser market.
The PDM Series includes 4 models:
→ PDM+ and PDM+HP : Single-mode output fiber; High power (up to 3.5W);
→ PDM4+ and PDM4+ HP: Dual Wavelengths (980 and 1064 nm); Single-mode output fiber; High power (up to 10W)
Key features:
→ Single-shot, burst mode or CW operation
→ Up to 10W peak power
→ Pulse duration: 1 nsec to CW (FWHM)
→ From one-shot to 250 MHz repetition rate
→ Extremely low jitter (<8ps)
→ Large range of wavelengths
→ Excellent beam quality
→ Low N.A.
→ Software et DLL included for computer driving
Key applications:
→ MOPA architecture
→ Low power micromachining
→ Laser development
→ Non destructive control
→ Telemetry
→ Doppler measurements
→ Metrology
→ Semiconductor testing
