Femtosecond pulse propagation in the gain region of laser amplifiers and applications to subpicosecond switching

Research output: Contribution to conferencePaper

Abstract

Experiments were performed to investigate the femtosecond laser pulses with high-enough intensity tune inside the gain region of laser amplifiers. Transmission and cross-correlation measurements were performed using 135-fs FWHM pulses propagating through a semiconductor laser diode amplifier prepared with anti-reflection coated facets. A self-modelocked Ti:sapphire laser operating at 90 MHz was tuned across the bandedge of a laser diode with 30 mA of injection current. The laser was tuned to the peak of the gain, and the transmission of the laser diode as a function of input pulse energy was measured. The laser diode initially exhibited gain saturation as the input pulse energy continued to decrease as the pulse underwent induced absorption.
