In this paper, we demonstrate a tunable mid-infrared (mid-IR) optical parametric oscillator
(OPO) using an MgO: PPLN crystal with a polarization period of 29.8 μm, which was end …

We present a theoretical investigation of coupling efficiency of a laser diode to a single-
mode circular core triangular index fiber coupling via upside-down tapered hemispherical …

An 808 nm laser diode (LD) end-pumped passively Q-switched Nd: YAG ceramic yellow
green laser at 561 nm with high stability and low noise has been demonstrated, for the first …

Optical systems are becoming increasingly important by resolving many bottlenecks in
today's communication, electronics, and biomedical systems. However, given the continuous …

We characterize laser generation in an ultralong air cavity (several meters in length) using
an optical-pumped semiconductor gain chip for laser wireless charging applications. The …

An optical resonator usually consists of mirrors or lenses which are configured in such a way
that the beam of light is confined in a closed path. Resonators are fundamental components …

A folded cavity of LD side-pumped acousto-optically Q-switched Nd: YAG/SrWO 4 solid-state
Raman laser is designed. The effects of the thermal focal length and resonator length on the …

A doubly Q-switched (DQS) Ho: LuAG laser resonantly pumped by a 1.91-μm laser was first
presented with an acoustic-optic modulator (AOM) and a Cr^ 2+: ZnS saturable absorber. A …

The regularities of the transformation of the intensity profile of a collimated Gaussian wave
beam formed by the control optical system at the exit of an long path are experimentally …
