CONSTITUTION: A raman laser resonator includes a pump resonator(10) provided with a rear mirror(1) and a laser rod(3) and Raman conversion unit(20) provided with a condense lens(6), Raman medium(7) and a collimating lens(8). The pump resonator(10) generates a pump laser light. The Ranman conversion unit(20) converts the wavelength of the pump laser light by the induced Raman scattering effect. A partial reflection coating is formed on the surface(14A) facing to the pump resonator(10) and a dichroic reflection coating is formed on the surface(14B) facing to the Ranman conversion unit(20). And, an optical transparent plate(14) is installed perpendicular to the optical axis between the pump resonator(10) and the Ranman conversion unit(20).

Abstract: PURPOSE: A wavelength selection device having optical alignment stability for a double wavelength laser by using prisms is provided to not need laser rearrangement or target re-aiming by preventing the change of an optical axis in a wavelength conversion process. CONSTITUTION: An Nd:YAG pump oscillator generates pump lasers of a source wavelength. A folding prism set(130) is located between the pump oscillator and a wavelength converter. The folding prism set selectively outputs the pump lasers and wavelength conversion lasers. A spinning table(180) rotates the folding prism set at a lower portion of the folding prism set. The wavelength converter receives the pump lasers of the source wavelength coming from the pump oscillator through the folding prism set and a connection prism(140). The wavelength converter provides the wavelength conversion lasers of a changed wavelength. Two folding prisms are arranged on an incident plane of the pump lasers.

Abstract: The present invention is a wavelength selection device equipped with an OPO resonator and an optical filter. A nonlinear crystal and the optical filter interwork and reciprocate in one direction. The nonlinear crystal and the optical filter are moved by a guide rail extended in one direction, a guide block, and a motor. Therefore, the quality of a laser is improved by minimizing optical axis transformation in movement due to the guide rail and the guide block. The wavelength selection device is formed in a relatively simple structure so as to facilitate the installation in a confined space and reduce manufacturing costs.

Abstract: A raman laser generating method and generator by using a stimulated brillouin scattering are disclosed. In the method, an initial light is generated. By focussing the initial light into a gas cell(2), a portion of a laser beam is simulated raman scattered and the remainder is stimulated brillouin scattered. The simulated raman scattered laser beam is outputted through a collimate lens(1) and the simulated brillouin scattered laser beam returns to a front face(13A) of focussing lens(1). An amplified simulated raman scattered laser beam is scattered in gas cell(2) and outputted.
