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

The availability of high-power and high-brightness blue diode lasers makes them attractive as low-cost pump sources for broadly tunable Alexandrite lasers. In this paper we investigate the performance of an Alexandrite laser pumped by a high-power fi

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
