Abstract

Fluoride-type crystals (CaF₂, SrF₂) doped with neodymium Nd³⁺ and codoped with buffer ions for breaking clusters of active ions and increasing fluorescence efficiency, present interesting alternative as laser active media for the diode-pumped mode-locked lasers. In comparison with widely used materials as Nd:YAG or Nd:YVO₄, they have broad emission spectra as well as longer fluorescence lifetime, in comparison with Nd:glass, SrF₂ and CaF₂ have better thermal conductivity. In spite of the fact, that this thermal conductivity decreases with Nd³⁺ doping concentration, these crystals are alternative for the Nd:glass in subpicosecond mode-locked laser systems. In this paper we review the basic results reported recently on these active materials and in the second part we present our results achieved in low power diode pumped passively mode locked lasers with Nd,La:CaF₂ and Nd,Y:SrF₂ crystals. The pulses as short as 258 fs at wavelength of 1057 nm were obtained in the first case, while 5 ps long pulses at 1065 nm were generated from the second laser system.
