PLD905 Series 905 nm Pulsed Laser Diode
PLD905-25W-P
25 W peak, 905 nm, uncollimated
The PLD905-25W-P is a 25 W peak-power 905 nm pulsed laser diode built on stacked tunnel-junction technology with 3 emitters. It delivers 1 - 100 ns pulses and roughly 2.5 uJ of pulse energy at a 100 ns pulse width, and it ships in a Plastic SMD package. Beam divergence is 9 deg parallel and 25 deg perpendicular to the junction.
