Passive Q-switching of a Tm: YLF laser with a Co 2+ doped silver halide saturable absorber Academic Article uri icon

abstract

  • Abstract We report a successful passive Q-switching of a Tm: YLF laser operating at λ= 1.9 μm, using a Co 2+: AgCl 0.5 Br 0.5 saturable absorber. Approximately 200-ns long, 150 μJ pulses were obtained. Increase in pump energy resulted in repetitive pulsing, with a repetition rate approximately proportional to the pump pulse energy. Room-temperature optical transmission saturation curves measured in∼ 1-mm thick Co 2+: AgCl 0.5 Br 0.5 plates yielded a ground state absorption cross section View the MathML source
