An optical mount includes a mount material in a closed geometry with an outer surface sized for matching internal dimensions of an outer housing, and an inner surface including spaced apart inward extending contacting features providing contact points that collectively define an inner opening sized for securing an optical device including a crystal within. At least one feature gap or a recessed portion is between the inward extending contacting features. Edge holders are adapted for receiving corners of the optical device can be the protrusion pair or inner notches. The outer surface includes at least one outer notch between the inward extending contacting features. The edge holders and outer notch(es) are for each acting as hinge points opening or pinching depending on a direction of force on the optical mount for responding with flexure when there is a dimensional change in the crystal, mount material, or the housing.

Mounting ring for maintaining optical device alignment

An optical device includes an optical assembly having a housing, a first end window, and a second end window. The first and second end window together with the housing provide an enclosed volume for a protected optical device including an optical material. A material for the end windows blocks essentially all non-pass band light having sufficient energy to generate absorption phenomena in the optical material while transmitting essentially all of operational wavelength light (pass band light) for the optical device. A material for the housing also blocks essentially all the non-pass band light from reaching the optical material.

Optical assembly for protection of optical devices

A crystal capture housing (housing) for cooling an optical device including a crystal having optical end faces and non-optical faces spanning a length between the optical end faces. An outer housing body (body) has end openings and a crystal mount assembly (CMA) includes a thermally conductive material having end openings connected to an internal opening sized to mount the crystal therein. The CMA thermally contacts each of the non-optical faces of said crystal. The CMA includes a plurality of embedded liquid coolant conduit channels (coolant channels) formed therethrough spanning the length, and the CMA is sized to fit within the body and provide an air gap between the CMA and the body.

An acousto-optic modulator includes a (100), (010) or (001) single crystal silicon acousto-optic interaction medium, and at least one transducer for emitting an acoustic wave attached to the single crystal. The transducer has a first electrode layer disposed on one side and a second electrode layer disposed on its other side. The transducer is aligned to the single crystal so that the direction of acoustic propagation in the silicon crystal is substantially along the (100), (010) or (001) direction. A q-switched laser includes a modulator according to the invention.
