Abstract:
A laser system, comprising:a gain medium and a resonator for generating a laser beam; a wavelength selection unit for adjustably narrowing and tuning the beam; a beam linewidth and wavelength monitoring unit; and a processor configured to communicate with the beam monitoring unit and the wavelength selection unit, wherein values of the linewidth and the wavelength of the beam are monitored by the processor and adjusted to selected values, wherein the wavelength selection unit includes a first prism which is rotatably adjustable using the processor for controlling the linewidth of the beam, wherein the wavelength selection unit further includes one of a grating and a highly reflective mirror which is orientationally adjusted by the processor for controlling the wavelength the beam, wherein the wavelength selection unit further includes a second prism which is rotatably adjusted by the processor for compensating a refraction angle from the first prism when the first prism is rotated.
