| 20100128343 | WAVELENGTH CONVERSION LIGHT SOURCE APPARATUS AND WAVELENGTH CONVERSION METHOD - A wavelength conversion light source apparatus includes a fundamental wave light source configured to emit a fundamental wave, a nonlinear crystal configured to convert a wavelength of the fundamental wave by being irradiated with the fundamental wave and making the fundamental wave pass therethrough, and a movement unit configured to place the nonlinear crystal thereon and continuously move the nonlinear crystal within a plane, where a phase matching condition is not violated, so that a passage path of the fundamental wave passing through the nonlinear crystal is changed. | 05-27-2010 |
| 20090073417 | COHERENT DOPPLER LIDAR - A coherent Doppler lidar which can oscillate high energy pulses and output laser beams in a longer wavelength range of 1.5 μm to the atmosphere is provided. The coherent Doppler lidar has a pulse laser an oscillation wavelength of which is controlled by means of injection locking of a seed light output from a master laser, wherein the pulse laser is a type in which a laser medium is disposed in a resonator, a pulse light of a predetermined repetition frequency is input to the laser medium as an excitation light, whereby pulse laser oscillation is generated in the resonator to output pulse laser beams from the resonator, and the laser medium being a type which has at least a region having Tm, Ho:YAG ceramics, and is excited by the excitation light to output pulse laser beams in 2 μm wavelength band. | 03-19-2009 |
