Abstract

In this paper, we present the experimental results obtained with Tm:YVO₄ and Tm,Ho:YLF active medium pumped in an active mirror configuration. Optical to optical efficiency, beam quality and spectral characteristics obtained for both crystals are compared. Extensive research is being devoted to the development of solid state lasers emitting in the eye safe spectral range with the possibility of efficient diode-pumped sources. There is a promising range of applications foreseen for such devices including LIDAR, metrology and medical applications. The microchip concept, where the mirrors are coated directly on the crystal faces polished parallel, allows to set up in very compact sources with high spatial quality beams. Resulting from the compactness of the cavity, these lasers are very stable. We present in this paper the results obtained in our laboratory for both Tm:YVO₄ and Tm,Ho:YLF microchip lasers.
