High-power 1.5μm laser diodes for LIDAR applications

We report on the development of high peak power laser diodes emitting in the 1.5 \mu \mathrm {m} wavelength band for eye-safe LIDAR applications. Different techniques for wavelength locking to and operation with a narrow emission spectrum are discussed. Furthermore, we review the strategies to incre...

Description
Summary:We report on the development of high peak power laser diodes emitting in the 1.5 \mu \mathrm {m} wavelength band for eye-safe LIDAR applications. Different techniques for wavelength locking to and operation with a narrow emission spectrum are discussed. Furthermore, we review the strategies to increase the beam brightness. Recent progress in new epitaxial layer designs enabling high peak powers is also discussed. Finally, we discuss the performance of the laser diodes in terms of improvements they render possible for high-performance LIDAR systems.
