Micro-pulling-down grown Tm,Ho:GSAG crystal as laser gain medium

Popis výsledku v původním jazyce

In this work, we explored a Tm,Ho co-doped GSAG crystal grown by the μ-PD method as active laser medium for generation around the wavelength of 2.1 μm. We investigated laser performance under pulsed excitation at both 0.8 μm and 1.7 μm, as well as continuous-wave excitation at 1.7 μm. Special attention was given to the tunability of the laser emission wavelength. Successful laser generation was achieved with slope efficiency reaching up to 30%, and a wavelength tuning range up to 138 nm. Our results demonstrate that μ-PD grown Tm,Ho:GSAG crystal represents a promising gain medium for widely tunable 2.1 μm lasers, highlighting the advantages of the μ-PD growth method for efficient and economical laser crystal fabrication.
