Abstract
The thulium microlasers based on yttriumaluminium perovskite and yttriumaluminium garnet crystals are considered as coherent light sources at the wavelength near 2 μm The comparative analysis of these lasers is carried out by means of the lasers’ parameters optimization for each value of the pumping power taking into consideration the crossrelaxation and upconversion processes as well as heating of the active medium The optimal values of the active medium length activator concentration and the output mirror reflectivity are determined both for TmYAP and TmYAGlaser The pulse generation of TmYAP and TmYAGlasers is also considered the parameters of this regime are determined The comparison shows the suitability of TmYAP laser crystal both for cw and pulse generation The upconversion influence on the laser characteristics is also analyzed
