Abstract
A simultaneous temperature- and wavelength-insensitive parametric amplifier comprising a pump laser, a signal laser, and a crystal amplifier. The pump laser system on a first optical pathway includes a Nd:YVOlaser oscillator-regenerative amplifier and a Nd:YAG boost amplifier. The pump laser beam is generated from the pump laser system, passes through the first image-relay system, and is frequency-doubled in the frequency-doubling crystal. The signal laser system on a second optical pathway comprises a Ti:sapphire regenerative amplifier and generates the signal laser beam, which passes through the pulse stretcher and is temporally chirped and imposed with an angular dispersion by the first grating. The chirped signal beam and pump laser beam are intersected with a noncollinear angle of >5° in the crystal amplifier for temperature-insensitive phase-matching (PM). By optimizing grating constant of the first grating, the chirped signal is imposed with appropriate amount of angular dispersion for wavelength-insensitive PM.
