Title:
【発明の名称】ポンプレーザと光パラメトリック発振器の両者の単一共振器空洞にブリュースター角度のQスイッチを有するアイセーフレーザを使用するレンジ発見システム
Document Type and Number:
Japanese Patent JP3410108
Kind Code:
B2
Abstract:
An eyesafe laser (10) transmitter having a single resonator cavity (16) for both the pump laser and the optical parametric oscillator (22). A Nd:YAG rod (24) provides gain for light at a first wavelength. A combined Q-switch/Brewster plate (26) Q-switches the light to increase its intensity and polarizes the light so that its polarization plane is perpendicular to the Z-axis of a KTP crystal functioning as the optical parametric oscillator, thereby providing type II phase matching conditions. The optical parametric oscillator transforms the light at the first wavelength to light at a second wavelength which is output thorough a partially reflective outcoupler at a wavelength which will not harm the eyes.
