Characteristics of a flowing He-SrCl2 vapor laser

An experimental investigation on the characteristics of a flowing He-SrCl2 vapor laser is carried out. The output power as a function of the SrCl2 vapor pressure is presented by calculating the radial temperature distribution of the discharge tube. The temporal dependences of the discharge current pulse on the laser pulses at 1 μm, ∼ 3 μm and 6.45 μm lines in strontium atom and ion, as well as the spot modes of the laser beam are measured and analyzed under different laser output power.
