1. A radiation output device comprising:
a radiation generating module configured to generate initial radiation;
a filter module configured to reflect a portion of a first preset wavelength of the initial radiation to the radiation generating module and transmit a portion of a second preset wavelength of the initial radiation, the transmitted radiation is therefore used as an output radiation of the radiation output device;
a detection feedback module, using a portion of or all of the output radiation as a feedback radiation, configured to instruct a modulating module to modulate the filter module according to the feedback radiation; and
an optical splitter module configured to split the output radiation to obtain the feedback radiation and a subsequent output radiation;
wherein the modulating module is connected to the filter module and configured to modulate a position and an angle of the filter module according to the instruction of the detection feedback module;
wherein the feedback radiation is configured to serve as an incident light of the detection feedback module, the subsequent output radiation is configured to serve as a work power supply;
wherein the feedback radiation is the detection feedback module comprises the following modules: a wave-locking module, a photoelectric conversion module and a driver module;
wherein the wave-locking module is configured to transmit the feedback radiation so as to select out partial radiation that meets a preset requirement;
the photoelectric conversion module is configured to convert the partial radiation that meets the preset requirement into an electric signal; and
the driver module is configured to send a control signal to the modulating module according to the electric signal, and the control signal is configured to control the modulating module to modulate the position and the angle of the filter module.
