Unstable laser resonators with super-Gaussian mirrors.
TLDR
A super-Gaussian mirror, built by a special evaporation technique, has been tested in an unstable resonator of a pulsed Nd:YAG laser, demonstrating its effectiveness in generating diffraction-limited beams.Abstract:
A new class of tapered reflectivity mirrors with a super-Gaussian profile R ∝ exp(−krn) is introduced, and a geometrical-optics approach for analysis and design of unstable resonators made with these mirrors is presented. A super-Gaussian mirror, built by a special evaporation technique, has been tested in an unstable resonator of a pulsed Nd:YAG laser, demonstrating its effectiveness in generating diffraction-limited beams.read more

Beam shaping profiles and propagation
TL;DR: In this article, the normalization of different functions, comparisons of profile shapes using different parameters within each family, the slope of the profiles at the half-height point of the irradiance, and two conditions that permit matching shapes of profiles from different families.

Super-Gaussian resonators for long-pulse XeCl lasers
TL;DR: Near-diffraction-limited laser beams of high energy have been achieved with a long-pulse (110-ns) XeCl laser fitted with a super- Gaussian unstable cavity of magnification M = 2.7 when the super-Gaussian output coupler is replaced with a hard-edge aluminized mirror.
Theoretical analysis and design of high-performance frequency converters for LIDAR systems
TL;DR: In this paper, the performance and spectral properties of an end-pumped Titan-Saphir laser transmitter were modeled with a rate-equation approach for stable and unstable resonators.

Fractional Fourier transform of flat-topped multi-Gaussian beams.
TL;DR: The fractional Fourier transform of the flat-topped multi-Gaussian beam (FMGB) is investigated based on the three kinds of FRFT optical systems: Lohman I, Lohmann II, and quadratic graded-index systems, and results show that the three types of FR FT optical systems have the same function when the apertures are ignored but that significantly different characteristics are exhibited when theApertures appear.
