905nm 75W Pulsed LD
The LDP905 series pulsed laser diodes feature stripe widths of 30µm to 220µm and can be stacked three or four emitters to realize the output power 15W to 150W. The high optical output and high density emission performance translate to superior beam performance which contributes to higher accuracy and expands longer distances in various LiDAR applications. A hermetically sealed TO can package ensures high reliability and temperature stability.
LDP-905075-3S-18 is a 75W infrared high peak power laser diode with 190x10µm emitting area. Adopted the industry TO18 hermetic package, the diode is laser range finders, surveying equipment, and security applications.
Features
ü Suited for short laser pulses from 1 to 200 ns
ü 3 epi-stacked emitters structure for high density emission
