Study of tunable resonances in laser beam divergence and beam deflection
Tunable radiofrequency resonances noise of lasers beam-width fluctuation beam-deviation fluctuation
2012/5/29
New, fundamental resonant properties of laser resonators are theoretically predicted and experimentally demonstrated. These resonances occur either in the time dependence of the beam width and that of...
Comparison of hard x-ray production from various targets in air using a short pulse kHz laser with photon production from a high power multifilament laser beam from the same targets in air
multifilament short pulse kHz laser
2011/9/5
Over the last few years there has been much interest in the production of hard X-rays from various targets using a kHz short pulse laser at intensities above 1014Wcm-2 (A). Most of these studies have ...
Phase disorder on laser beam combining in a Talbot resonator
Talbot resonator laser beam combining a six-core and a twelve-core photonic crystal fiber
2011/8/31
We study the role that phase disorder plays in the mode discrimination characteristics of a Talbot resonator.Two cases considered here correspond to a six-core and a twelve-core photonic crystal fiber...
