    • An optically controlled selector comprises an optical coupler (1) having a first input (2) for an optical input signal, a second input (3) for an optical control signal and an output (4) for a combined signal, and a resonant cavity (5) downstream of the output of the coupler (1) and arranged to receive the combined signal. The resonant cavity (5) contains an optically non-linear material so that changes in the power of the optical control signal result in changes in the resonant frequency of the cavity (5). In use, the power of the optical control signal controls transmission or suppression of the optical input signal through the optical cavity. Such a selector acts as a simple switch or to select one from a number of optical signals of different wavelength. Preferably the optical material is active and the optical cavity (5) formed by semiconductor laser amplifier.
    • 光控选择器包括具有用于光输入信号的第一输入(2)和用于光控制信号的第二输入(3)和用于组合信号的输出(4)的光耦合器(1),以及谐振腔 (5)在耦合器(1)的输出端的下游并被布置成接收组合信号。 谐振腔(5)包含光学非线性材料,使得光学控制信号的功率变化导致空腔(5)的谐振频率的变化。 在使用中,光控制信号的功率控制通过光腔传输或抑制光输入信号。 这样的选择器用作简单的开关或从多个不同波长的光信号中选择一个。 优选地,光学材料是有源的,并且由半导体激光放大器形成的光学腔(5)。

    • A laser system includes first and second mirrors, a semiconductor laser and a high frequency pulse generator. The semiconductor laser generates optical power within an optical cavity and reflects the optical power between the first mirror and second mirrors. The optical power has a frequency of f original-laser . The high frequency pulse generator generates a high frequency pulse with a rise time greater than an optical cycle of the optical power within the optical cavity and directly impinges the high frequency pulse on the optical power within the optical cavity. Impinging the high frequency pulse on the optical power within the optical cavity causes a frequency shift of the optical power to generate a final laser frequency that is greater than f original-laser as well as beyond a frequency band of the second mirror to cause a final laser to be emitted past the second mirror and from the semiconductor laser.
    • 激光系统包括第一和第二反射镜,半导体激光器和高频脉冲发生器。 半导体激光器在光腔内产生光功率并且反射第一反射镜和第二反射镜之间的光焦度。 光功率具有原始激光的频率。 高频脉冲发生器产生高频脉冲,其上升时间大于光腔内光功率的光周期,并直接将高频脉冲冲击在光腔内的光功率上。 使高频脉冲对光腔内的光功率产生影响,导致光功率的频移,产生大于原始激光器的最终激光频率以及超出第二反射镜的频带以产生最终激光 被发射通过第二反射镜和半导体激光器。
