Abstract: An inventive composite optical gain medium capable includes a thin-disk gain layer bonded to an index-matched cap. The gain medium's surface is shaped like a paraboloid frustum or other truncated surface of revolution. The gain medium may be cryogenically cooled and optically pumped to provide optical gain for a pulsed laser beam. Photons emitted spontaneously in the gain layer reflect off or refract through the curved surface and out of the gain medium, reducing amplified spontaneous emission (ASE). This reduces limits on stored energy and gain imposed by ASE, enabling higher average powers (e.g., 100-10,000 Watts). Operating at cryogenic temperatures reduces thermal distortion caused by thermo-mechanical surface deformations and thermo-optic index variations in the gain medium. This facilitates the use of the gain medium in an image-relayed, multi-pass architecture for smoothed extraction and further increases in peak pulse energy (e.g., to 1-100 Joules).

Abstract: A monoblock laser cavity incorporates optical components for a short-pulse laser.

Abstract: In a laser light source apparatus using a wavelength converting device (35), the position and angle of the wavelength converting device are allowed to be varied so as to maximize the laser output. The angular adjustment of the wavelength converting device is simplified by accurately positioning the wavelength converting device. A holder (57) for retaining the wavelength converting device may be supported by a support portion (56) formed in a base (38) so as to be moveable in the depthwise direction of the poled inverted domain regions and tiltable with respect to the optical path. Preferably, the holder may be rotatable around an axial line substantially perpendicular to the optical axial line. In particular, the wavelength converting device may be fixedly attached to the holder so as to bring an exit surface (35b) of the wavelength converting device in close contact with a mounting reference surface (841) by using a bonding agent applied to a top surface (35e) and a bottom surface (35f) of the wavelength converting device adjacent to the exit surface, and a bottom surface (207) of a recess (891) formed in the holder adjacent to and in parallel with the mounting reference surface.

Abstract: A system and method for optical frequency conversion having asymmetric output include a coherent light apparatus. The coherent light apparatus includes a coherent light source that produces a first coherent light, a frequency converter optically coupled to the coherent light source, and a coupling optic optically coupled between the coherent light source and the frequency converter.

Abstract: An optical resonator with an optical mode has a resonator block with and opening. At least one optical component is mounted on a holder that is positioned in the opening to locate the component in the mode of the resonator. The holder is contrained by the resonator block so that the orientation of the component in the plane of the resonator is substantially fixed by the opening. The component is simply aligned in the resonator by rotating the holder in the opening. The resonator block may also have a mirror reference surfaces that automatically aligns a mirror that is pressed against the surface. The resonator has a high degree of optomechanical assembly and facilitates initial component alignment and the interchange of optical components and mirrors.
