Abstract

"In this work a delay-programmable two-color femtosecond laser based on a chirped-seed noncollinear optical parametric amplifier was characterized. This design utilizes a titanium-sapphire crystal oscillator to generate broadband pulses of light spanning approximately 600-1200 nm, with a pulse duration of ~5 fs, repetition rate of 80 MHz, and pulse energy of ~2.5 nJ. An infrared portion of the light, spanning approximately 1020-1060 nm, is split off from the pulse and used to generate a pump beam. By dispersing the remaining seed beam and controlling the relative timing delay between the seed and the pump, tunable frequencies within the seed can be amplified. This mechanism allows for two independently tunable beams to be generated with a controllable relative delay at high repetition rate. We use the light source to perform two interferometry measurements, a nonlinear optical cross-correlation and a dispersion scan, in order to characterize its temporal and spectral properties. We find qualitative differences between the results of these two measurement techniques and proposepossible sources of this difference"-- Abstract, p. iii
