Abstract

Single frequency generation was investigated in two types of diode pumped lasers: microchips and lasers with metallic thin film selectors. Principles and properties of both types of single frequency generation are discussed. Energetic output characteristics, spectra of generation, tuning ranges were measured and compared for both lasers. In case of microchips only Nd:YAG crystal was applied, whereas in case of metallic thin-film selector single frequency output was achieved in Nd:YAG, Nd:YVO₄ and Nd:YLF crystals. Up to 50 mW of power at single frequency in Nd:YAG microchip and 600 mW in Nd:YVO₄ laser with selector were obtained. Physical and technical limitations caused by the wide gain bandwidth, thermal effects and mechanical vibrations were discussed.
