A single-pass optical parametric amplifier is provided. The single-pass optical parametric amplifier comprises a light 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 supercontinuum generator extending the wavelength range of the fundamental wave to form a supercontinuum generation seed; and an optical parametric wavelength transformer transforming the supercontinuum generation seed and the second harmonic generation wave into a signal wave and an idler wave.

Wavelength tunable single-pass optical parametric amplifier

The present invention is a scanning system having spherical mirrors to operate a two-dimensional scanning. Aberration owing to oblique incident light is compensated to reach diffraction limit. With proper metallic coating, the present invention uses a wavelength from ultra-violet light to tera-hertz wavelength

Reflective optical scanning system having minimized aberration

A harmonic generation microscopy employs a laser device that emits a laser beam having a predetermined wavelength that causes no autofluorescence in a biological sample and that, after excited, induces both the second and third harmonic waves. The laser beam is projected onto a sample and an observation beam from the sample is received. The observation beam is directed through a splitter to separate the second harmonic wave and the third harmonic wave both of which are then converted into corresponding electrical signals. The electrical signals are fed to a computer-based image processing equipment to form an image of the sample on the basis of the second and third harmonic waves.
