High-Efficiency Ho:YAP Pulse Laser Pumped at 1989 nm
Crystals, 2021 A Tm:YAP laser with an output wavelength of 1989 nm was selected for the first time as the pump source of a Q-switched Ho:YAP laser. When the absorbed power was 30 W, an average power of 18.02 W with the pulse width of 104.2 ns acousto-optic (AO) Q ...

Interferometry and Laser Control with Solid Fabry-Perot Etalons [PDF]
, 1966 The use and analysis of solid Fabry-Perot etalons for interferometry and laser control are discussed and supported with experimental data. Low angle scattering is found to be an important factor influencing finesse and peak transmission.

Superposition of vortex beams generated by polarization conversion in uniaxial crystals
Scientific Reports, 2022 An optical system comprising a c-cut uniaxial crystal positioned between two axicons and illuminated by a Gaussian or a Laguerre–Gauss mode was used to demonstrate the generation of various vector vortex beams.
