External-cavity designs for phase-coupled laser diode arrays
External-cavity designs phase-coupled laser diode arrays
2010/11/16
We describe passive phase-locking architectures based on external-cavity setups to improve the brightness of diode laser bars. Volume Bragg gratings are used to stabilize the lase line. Numerical mode...

Detailed derivation of the master equation and the corresponding time evolution of the cavity
radiation of a coherent beat laser when the atoms are initially prepared in a partial coherent super-posi...
Multiple Patterning of Laser Focus Spot Using a Segmented Kinoform Phase Plate
Kinoform phase plate Computer-generated hologram Laser fusion
2009/6/8
An important technique required in the application of laser systems to fusion is the ability to generate high energy to satisfy the conditions for self-ignition and to improve the uniformity of laser ...
Laser Beams with Spatio-Temporal Phase Modulation
Coherence control Partially coherent light Speckle smoothing
2009/6/8
This paper reviews a method of the irradiance profile smoothing on the high-power laser system. In the multi-beam laser irradiation geometry, the coherence control of laser beam is necessary to reduce...
