Defining and Measuring Laser Beam Quality

1993
This lecture will review a very useful approach that has recently been developed for defining the transverse beam quality as well as other propagation parameters of arbitrary real laser beams. We will also describe a convenient new instrument for measuring the propagation parameters of high-power laser beams, and summarize the results of beam quality ...

Beam Quality In High-Power Laser Amplification

SPIE Proceedings, 1989
In order to contribute to the development of a reliable criterion for beam quality characterization, a review of the commonly used criteria is done. Several meaningful experimental works using oscillator-amplifier configurations for high power industrial CO2 lasers, are analyzed.

M2 beam-quality meter for pulsed lasers

OSA Annual Meeting, 1993
Laser beam quality measurements have become important diagnostics for laser operation and beam propagation. A commercial instrument, based on the M2 method of defining beam quality,1 has been developed for CW lasers.2 We have constructed and tested an equivalent instrument for measuring the beam quality of a single shot of a pulsed laser.

Beam quality and coherence evolution impulsed lasers

Conference Digest. 2000 Conference on Lasers and Electro-Optics Europe (Cat. No.00TH8505), 2002
Summary form only given. It is now well established that laser pulses, whose duration is not much larger than the transit time inside the cavity, undergo a beam-parameter evolution (concerning spot size, radius of curvature, far-field divergence, etc.) during the pulse life, from its beginning to its end.
