Paper Abstract

The optical amplification and frequency conversion of a gain-switched 1532 nm distributed feedback (DFB) laser diode over a wide range of repetition rates are studied. A two stage Erbium fiber amplifier setup is pumped at 976 nm and operated at 1 to 80MHz pulse repetition frequency. The seed laser repetition rate is evaluated directly inside the pumping electronics to set the optimum pump power. Second-harmonic generation to 766 nm is achieved in a periodically poled lithium niobate bulk crystal. There is a high demand of several hundred milliwatt of picosecond pulsed laser power for stimulated emission depletion (STED) microscopy.
