Claim:
1. A simultaneous temperature- and wavelength-insensitive parametric amplifier system, comprising a pump laser system on a first optical pathway, the pump laser system comprising a Nd:YVO a first image relay system arranged on the first optical pathway after the pump laser system, a frequency-doubling crystal arranged on the first optical pathway after the first image relay system, a reflector on the first optical pathway arranged after the frequency-doubling crystal, a signal laser system on a second optical pathway, the signal laser system comprises a Ti:sapphire regenerative amplifier, a pulse stretcher on the second optical pathway after the signal laser system, a first grating arranged on the second optical pathway after the pulse stretcher, a second grating, a pulse compressor arranged along a same optical pathway after the second grating, an electronic phase-locking loop, and a nonlinear crystal amplifier, wherein the pump laser system and the signal system are synchronized with the electronic phase-locking loop; a 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; a signal laser beam is generated from the signal laser system, passes through the pulse stretcher, and is temporally chirped and imposed with an angular dispersion by the first grating; the chirped signal laser beam is amplified in the nonlinear crystal amplifier, and the amplified chirped signal laser beam is re-collimated by the second grating and compressed in the compressor; energy flows from the pump laser beam into the signal laser beam during amplification in the nonlinear crystal amplifier; and By adjusting a direction of the reflector in the first optical pathway, the signal laser beam and the pump laser beam are intersected with a noncollinear angle in the nonlinear crystal amplifier.
