PLD905 Series 905 nm Pulsed Laser Diode
PLD905BL-180W-M
180 W peak, 905 nm, uncollimated
The PLD905BL-180W-M is a 180 W peak-power 905 nm pulsed laser diode built on stacked tunnel-junction technology with 6 emitters. It delivers 1 - 100 ns pulses and roughly 18 uJ of pulse energy at a 100 ns pulse width, and it ships in a TO56 package. A low thermal-drift variant keeps the wavelength stable across temperature.
