Embodiment Construction
[0017] In order to further illustrate the features and structures of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] figure 1 It is a schematic diagram of a fast-tuning laser resonator device for grating selection. In the figure, a beam splitter 4, an energy meter 5 and a spectrometer 6 are used. The energy meter 5 is used to measure the output laser energy, and the spectrometer 6 is used to measure the wavelength of the output laser line.
[0019] The grating branch-selected fast-tuning laser resonator of the present invention is composed of a cavity (not shown in the figure), a laser output mirror 3, a grating 1, a grating turntable 11, a servo motor 2, a servo motor drive module 9 and an automatic control module. . The servo motor 2 is connected to the grating turntable 11 , serves as a driving mechanism for the grating turntable 11 , provides rotational power to the grating turntable 11...
