Abstract :
Red laser radiation of 15 W power at 0.63 μ was obtained by sum frequency generation of 1.55 μ and 1.06 μ radiation wavelengths from Er and Yb pulsed fiber lasers with 1 MHz pulse repetition rate respectively. Noncritical phase matching of lithium triborate (LBO) crystal at temperature 13°C was employed for sum frequency generation. The optical-to-optical conversion efficiency of 40% was achieved. The proposed technique allows obtaining high-power pulsed single-mode laser red radiation in 0.6 μ - 0.65 μ spectral region.
