Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0023] see figure 1 The optical path diagram and figure 2 The optical path diagram of the composite configuration tunable grating external-cavity dual-mode laser with slits in the optical path shown. Such as figure 1 As shown, the present invention discloses a compound configuration tunable grating external cavity dual-mode laser, which includes a gain device 1, a lens 2, a grating 3, and a plane mirror 4, wherein the end face 12 on one side of the gain device 1 is located at the focal point of the lens 2 plane, so that the light emitted by the end surface 12 on one side of the gain device 1 is collimated into parallel light after being passed through the lens 2, and the parallel light is incident on the surface of the...
