激光源装置以及全息照相设备
摘要：
本发明公开了一种激光源装置包括，可发射多模激光的激光二极管，第一光学元件，该第一光学元件可使该激光二极管发出的该激光准直，衍射光栅，该衍射光栅可沿朝向该激光二极管的方向之外的预定方向反射由该第一光学元件准直的激光中的零阶光以及可朝向该激光二极管反射由该第一光学元件准直的激光中的第一阶光，第二光学元件，该第二光学元件可沿预定方向反射由该衍射光栅反射的该零阶光，同时透射一部分由该衍射光栅反射的该零阶光，和第一探测装置，该第一探测装置可检测穿过该第二光学元件的光的波长和强度二者之中的至少一项。
摘要（英）：

A laser light source device includes a laser diode that emits multimode laser light, a first optical element that collimates the laser light emitted from the laser diode, a diffraction grating that reflects zero-order light in the collimated laser light in a predetermined direction other than a direction toward the laser diode and reflects first-order light in the collimated laser light toward the laser diode, a second optical element that reflects the zero-order light reflected by the diffraction grating in a predetermined direction while transmitting a part of the zero-order light reflected by the diffraction grating, and a first detector that detects at least one of a wavelength and an intensity of the light that passes through the second optical element.
