Applications of Semiconductor Laser Technologies

Space Laser Communications: Systems, Technologies, and Applications

Laser communication links in space are attractive alternatives to present-day microwave links. This tutorial describes the basic concept and the functions of an optical terminal on board a spacecraft. It points out the differences between free-space optical links on one hand and glass fiber systems and microwave directional links on the other hand. The requirements on data transmitters and rece...

Novel photonic applications of nonlinear semiconductor laser dynamics

With a proper perturbation, even a single-mode semiconductor laser can exhibit highly complex dynamical characteristics ranging from stable, narrow-linewidth oscillation to broadband chaos. In recent years, three approaches to invoke complex nonlinear dynamical states in a single-mode semiconductor laser have been thoroughly studied: optical injection, optical feedback, and optoelectronic feedb...

Short pulse laser technologies for advanced accelerator applications

Next generation short pulse laser systems for high energy accelerator physics have been developed using novel synchronization techniques. The basic techniques are the synchronization of a mode locked oscillator to an RF reference, synchronization of two mode locked oscillators, synchronization of a lowrepetition amplifier to the oscillator, and multiplexing of modular laser beams. We have devel...
