Abstract: A solid-state laser apparatus and method in which a laser crystal and a non-linear optical crystal are connected and unitarily combined by a spacer. An optical resonator is constructed between both ends thereof. An optical cavity where the laser light passes through is formed between the laser crystal and the non-linear optical crystal. An end surface of the laser crystal is treated by optical polishing to form a laser resonator in the optical cavity. Alignment between the crystal becomes unnecessary, and subsequent assembling is thus simplified. Fresnel reflection occurs on the end surface of a laser crystal treated only by the optical polishing due to an index of refraction coefficient difference.

Abstract: A diffractive optical element improves wavefront aberration for transmitted light. The diffractive optical element includes first and second substrates, an adhesive layer, a film, and an overcoat layer, all of which are formed of optically transparent materials. The film is glued on the first substrate via the adhesive layer. The film has a surface where a desired diffraction grating is formed in accordance with an irregularity thereof. The overcoat layer is formed on the film surface so as to fill a concave part of the diffractive grating. The second substrate is glued on the overcoat layer so as to make plane a surface of the overcoat layer. The adhesive layer and the film have an approximately equal refractive index.
