Abstract:
1. A single-pass optical parametric amplifier, comprising: a laser source emitting a fundamental wave having a wavelength range; a nonlinear material, which the fundamental wave passes therethrough to form a second harmonic generation wave having a light path; a dichroic mirror separating the fundamental wave and the second harmonic generation wave; a supercontinuum generator extending the wavelength range of the fundamental wave to form a supercontinuum generation seed; a translational stage controlling the light path of the second harmonic generation wave; an optical parametric wavelength transformer transforming the supercontinuum generation seed and the harmonic generation wave into a signal wave and an idler wave; a cold mirror making the supercontinuum generation seed and the second harmonic generation wave proceed in an identical path to pass through the optical parametric wavelength transformer; and a temperature controller controlling a temperature of the optical parametric wavelength transformer.
