Laser diode excitated solid state laser
专利汇可以提供Laser diode excitated solid state laser专利检索，专利查询，专利分析的服务。并且PURPOSE:To embody a laser diode excitated solid state laser having high output, high efficiency, and high spectrum purity by using a diffraction grating on a light wave guide passage as a Bragg reflector or a coupler for excitation light and adopting a high output diode as an excitation light source. CONSTITUTION:A diffraction grating 8, where spectra are set to z direction on a part of a light waveguide passage 7, is prepared. The diffraction grating 8 works as a Bragg reflector with laser light, and a coupler which couples excitation light emitted from a diode bar 3 with the light waveguide passage 7. When it is assumed that the angle between the excitation light and the diffraction grating is theta, the relation between excitation light wavelength lambda and pitches A and theta is represented by the following equation: The diode bar 3 is set so that it may be vertical to a junction side of an active laser of a laser diode and its angle with the ejection direction of laser light may be theta. A coupling optical system 6 is installed between the diode bar 3 and the diffraction grating 8. A small-sized collimator which parallel emitted light per discretes laser diodes which constitute diode bar or laser diode arrays.，下面是Laser diode excitated solid state laser专利的具体信息内容。
