Paper Abstract

We have demonstrated a new design of a four-pass dye laser amplifier that can suppress parasitic oscillation in a multi-pass amplifier. Amplified spontaneous emission (ASE) in the output beam of the amplifier is reduced with a diffraction grating. A high-peak power pulsed dye laser beam is obtained by amplifying a continuous-wave narrow-bandwidth dye laser with power gain greater than 2 X 106. The eventual bandwidth of the pulses is measured to be approximately 130 MHz. The obtained ASE ratio of the four- pass amplifier system is < 1.5%. Also, we have obtained a high-resolution coherent anti-Stoke Raman spectrum of oxygen in air using the laser system.
