2 kW Pulse Power from Internal Wavelength Stabilized Diode Laser Bar for LiDAR Applications

Abstract

We present a bipolar-cascade distributed-Bragg-reflector laser bar with an intended wavelength of 905 nm emitting 8 ns long pulses with 2 kW peak power at a current slightly above 1 kA into the third vertical mode. The spectral width of the pulses is 0.3 nm.
