We report the first ever demonstration of a wavelength-locked Alexandrite laser using a volume Bragg grating (VBG) as a wavelength-selective mirror. Output power of 3.3 W with a diffraction limited beam quality of M2=1.1 was obtained at a lasing wave

We present several strategies for increasing the output laser power of near-diffraction limited continuous-wave Alexandrite lasers pumped by fibre-coupled red laser diodes. Laser mode size control using a convex mirror with the varying thermal lens i

We report a blue-diode-pumped Alexandrite laser operating at 754nm with 0.5W of output laser power with an optical efficiency of 20%. We provide a comparison of blue-diode-pumping to red-diode-pumping to show its potential as a low-cost alternative d

Wavelength tunable and single frequency laser sources in the near-infrared are essential in addressing high resolution applications including Quantum Technologies and remote sensing. Alexandrite lasers are an attractive prospect for these application

This work presents a study of a fully nonastigmatic design of a single-longitudinal-mode, wavelength-tunable, unidirectional alexandrite ring laser cavity and assessment of its performance compared to more complex laser design requiring astigmatism c

We present an overview of pump-induced lensing effects in end-pumped Alexandrite lasers. The dioptric lens power is measured for a diode pumped Alexandrite laser using a Shack-Hartmann wavefront sensor under both non-lasing and lasing conditions. Und
