Abstract :
Efficient second-harmonic generation in praseodymium-doped gallium-lanthanum-sulphide glasses for optical fiber amplifiers around 1.3 μm is experimentally investigated. The Pr/sup 3+/-doped Ga:La:S glass samples were pumped by Nd:YAG laser pulses at 1.319 μm and 1.064 μm and generated frequency doubled light at 660 nm and 532 nm, respectively, with conversion efficiencies as high as 0.02%. Frequency doubling in praseodymium-free Ga:La:S glass samples was also observed.
