Abstract
Mode-locked operation of wavelength tunable Cr3+ doped LiSrAlF6 (CnLiSAF) and LiSr0.8Ca0.2AlF6 (Cr:LiSCAF) lasers at a repetition frequency of 82MHz has been achieved by optical pumping with a cw krypton laser. An acousto-optic modelocker was used to initiate the pulse formation and pulses of 150fs duration were directly produced from both lasers when an intra-cavity two prism sequence was incorporated for cavity dispersion compensation. The low threshold characteristics of these lasers make Cr doped LiSAF and LiSCAF crystals promising solid state laser materials in the realization of compact, diode pumped, mode-locked, wavelength tunable laser systems.
