Narrow-Bandwidth, Subnanosecond, Infrared Pulse Generation in PPLN Pumped by a Fiber Amplifier-Microchip Oscillator

Narrow-bandwidth, 0.5 ns IR pulses were achieved in a periodically poled lithium niobate optical parametric generator (PPLN OPG). The OPG was pumped at 7.14 kHz by a Yb-doped fiber amplifier and a microchip Nd:YAG oscillator. Bandwidth was reduced from 3.6 nm to 55 pm using a continuous-wave (CW) 1....

Description
Summary:Narrow-bandwidth, 0.5 ns IR pulses were achieved in a periodically poled lithium niobate optical parametric generator (PPLN OPG). The OPG was pumped at 7.14 kHz by a Yb-doped fiber amplifier and a microchip Nd:YAG oscillator. Bandwidth was reduced from 3.6 nm to 55 pm using a continuous-wave (CW) 1.5-mum seed beam guided through the fiber amplifier.
