| Abstract: | Generation of visible light at 588 nm with peak power as high as 20 W through efficient frequency upconversion of 1.313 μm Q switched and mode locked Nd∶YLF laser pulse in a standard communication single mode germanosilicate optical fiber is reported. The conversion efficiency is measured to be 0.09% in 21 m fiber at 24 kW peak pump power. A blue green light with multi peak continues spectrum structure at 46￣560 nm generated by three wave sum frequency is also observed. The frequency upconversion process of blue green light is competing with the process of generation visible light at 588 nm. |
