PLD905 Series 905 nm Pulsed Laser Diode
PLD905-600W-MA
600 W peak, 905 nm, uncollimated
The PLD905-600W-MA is a 600 W peak-power 905 nm pulsed laser diode built on stacked tunnel-junction technology with 9 emitters. It delivers 1 - 100 ns pulses and roughly 30 uJ of pulse energy at a 100 ns pulse width, and it ships in a Metal stack package. Beam divergence is 10 deg parallel and 22 deg perpendicular to the junction.
Estimated range
- Retro-reflective target2.1 km
- Diffuse terrain690 m
Range figures are engineering estimates for a matched-filter receiver, 36 mm receive aperture and 90 % optical efficiency. See the range equation article for the full derivation.
