摘要： A planar waveguide laser device forms a waveguide by a plate-like laser medium (1) having birefringence and clad (2a, 2b) attached to at least one of the surfaces of the laser medium (1) perpendicular to its thickness direction, amplifies laser light by a gain produced by excitation light incident on the laser medium (1), and performs laser oscillation. The laser medium (1) is formed of a material having an optic axis on a cross section perpendicular to the light axis, which is the laser travelling direction. The clad (2a, 2b) is formed of a material having a refractive index in a range between refractive indexes of two polarized lights that travel along the light axis in the laser medium (1) and have oscillation surfaces that are orthogonal to each other. The planar waveguide laser device readily oscillates linearly polarized laser light.

摘要： A method for making a microchip laser includes preparing a laser-cavity chip assembly comprising a gain media, a first substantially flat surface, and a second substantially flat surface parallel to the first substantially flat surface. The method also includes forming a first reflective film on the first substantially flat surface to form a first cavity mirror, forming a second reflective film on the second substantially flat surface to form a second cavity mirror, and patterning at least one of the first reflective film or the second reflective film by removing at least a portion of the reflective film in the outer portion to form a center reflective portion in the one of the first reflective film or the second reflective film. The first cavity mirror and the second cavity mirror can suppress higher order transverse modes and produce a single TEM00 mode in the lasing light.

摘要： A wavelength conversion laser device includes a solid-state laser element having a waveguide structure including a laser medium that amplifies laser beams by providing a gain generated due to absorption of pump light to the laser beams and outputs a fundamental wave, and a wavelength conversion element having a waveguide structure including a nonlinear optical material that converts a part of a fundamental wave output from the solid-state laser element to a second harmonic, to resonate the fundamental wave by an optical resonator structure including the solid-state laser element and the wavelength conversion element and outputs a second harmonic from the wavelength conversion element. The solid-state laser element outputs a linearly polarized fundamental wave, and differentiates a polarization state of a fundamental wave having passed through the wavelength conversion element and entering into the solid-state laser element from linear polarization output from the solid-state laser element, so that wavelength conversion efficiency of the wavelength conversion element is not decreased in a peak wavelength of a gain band.

摘要： An optical fiber amplifier system is described and comprises a first optical fiber having a doped core with a first gain spectral profile upon being pumped. The first optical fiber is adapted to receive an optical signal from a light source. A second optical fiber has a doped core with a second gain spectral profile upon being pumped. The second optical fiber is optically coupled to the first optical fiber. A continuous wave pump light system is optically coupled to the fibers so as to store energy in the fibers for a subsequent amplification of the optical signal from the light source. An overlapping configuration is provided between the first gain spectral profile and the second gain spectral profile so as to reduce energy depletion in one of the optical fibers from amplification of spontaneous emission generated by another of the optical fibers.
