| 摘 要： | 提出利用旋转双光楔的方法来实现外腔半导体激光器波长的精密调谐.双光楔中,较大楔角的光楔用于粗调,较小楔角的光楔用于细调.与传统的Littman结构光栅外腔半导体激光器相比,通过这种方法,波长的精密调谐无需机械调谐装置,手动即可实现;对调谐的机械要求以及对振动的敏感性降低,波长选择精度相应大大提高.

| Abstract: | On basis of the traditional Littman configuration external cavity diode laser.In this paper,a novel method for wavelength selection is described by adding rotatable double wedge prisms system having different wedge angle to Littman configuration.In the system,the wedge prism with bigger wedge angle is used for coarse selection,and the other one with smaller wedge angle is used for fine selection.It comparing with Littman configuration,fine wavelength tuning can be implemented without complex mechanism by this way.At the same time,sensitivity for vibration is decreased and the wavelength selection accuracy can be greatly improved. |
