PLD905 Series 905 nm Pulsed Laser Diode
PLD905-140W-M
140 W peak, 905 nm, uncollimated
The PLD905-140W-M is a 140 W peak-power 905 nm pulsed laser diode built on stacked tunnel-junction technology with 4 emitters. It delivers 1 - 100 ns pulses and roughly 14 uJ of pulse energy at a 100 ns pulse width, and it ships in a TO56 package. Beam divergence is 9 deg parallel and 25 deg perpendicular to the junction.
