We describe recent experiments on generation and applications of amplitude-squeezed states of light from a semiconductor diode laser. Amplitude-squeezed light with intensity noise 2 dB below the standard shot- noise limit was observed from a diode laser with a weak optical feedback from an external grating. Applications of this amplitude-squeezed light as a local oscillator in heterodyne detection in Doppler velocity measurement and weak light-scattering measurement are discussed.
我们描述了近期关于从半导体二极管激光器产生光的振幅压缩态及其应用的实验。通过具有来自外部光栅的弱光反馈的二极管激光器，观察到了强度噪声比标准散粒噪声极限低2 dB的振幅压缩光。讨论了这种振幅压缩光在多普勒速度测量和弱光散射测量中的外差检测中作为本地振荡器的应用。
