技術說明

一種高脈衝重複率雷射裝置，具有一直線型腔體，該直線型腔體具一第一方向和相反於該第一方向的一第二方向，且沿該第一方向配置有：一第一光學元件、一增益與拉曼介質、一聲光晶體、一第一三硼酸鋰(LBO)晶體、以及一第二光學元件。該第一光學元件接收沿該第一方向入射的一泵浦光；該增益與拉曼介質接收來自該第一光學元件的該泵浦光，並產生具有 一第一波長的一第一紅外基礎雷射光和具有一第二波長的一第二紅外基礎雷射光；該聲光晶體接收來自一射頻控制器的一射頻控制信號，其中具有一高脈衝重複率的該射頻控制信號具有一信號週期，該信號週期包含一低位準期間及一高位準期間，且該聲光晶體依據該低位準期間，經歷相應的開通時間，俾使任何光線通過；該第一三硼酸鋰(LBO)晶體，接收來自該增益與拉曼介質的該第一和該第二紅外基礎雷射光，並產生具有一第三波長的一可見雷射光。 A high repetition rate pulse laser with a linear cavity having a first direction and a second direction opposite to the first direction. Along the first direction, the linear cavity includes: a first optical component, a gain and Raman medium, a acusto-optic crystal, a first LBO crystal, and a second optical element. The first optical component allows a pumping light to transmit therethrough and incident in the first direction. The gain and Raman medium receives the pumping light from the first optical component and enerates a first infrared base laser having a first wavelength and a second infrared base laser having a second wavelength. The acousto-optic crystal receives a radio frequency control signal from a radio frequency controller, wherein the radio frequency control signal with a high pulse repetition rate has a signal period including a low level period and a high level period, and the acousto-optic crystal undergoes a corresponding turn-on time to allow any light to pass through according to the low level period. The first LBO crystal receives the first and second infrared base lasers and generates a first visible laser having a third wavelength.
