Specifically, the light source 1 includes an IPL tube and a reflector configured to collect light emitted from the IPL tube and guide the collected light onto the incident surface 21 of the optical waveguide element 2.

In the embodiment of the present invention, the filter film 3 is a band-pass filter film, which can filter the light beam below a certain wavelength and the light beam above a certain wavelength, and retain the light beam in the required preset wavelength range.
In a preferred embodiment, the optical waveguide element 2 is configured as solid sapphire.

Alternatively, as shown in fig. 4, the filter 3 is provided on the exit surface 232 of the window sheet 23. It can be understood that, in this embodiment, the light beam emitted by the light source 1 is first incident on the incident surface 21 of the light waveguide element 2 and reflected in the light waveguide element 2, where the reflection refers to that the light beam is totally reflected on the boundary by using an incident angle greater than a critical angle, and then propagates along a broken line path, and finally, the light beam is emitted onto the incident surface 231 of the window sheet 23 through the emitting surface of the light waveguide element 2, where the emitting surface 22 of the light waveguide element 2 is partially overlapped with the incident surface 23 of the window sheet 23 in fig. 4, and passes through the emitting surface 232 of the window sheet 3, because the filtering film 3 is disposed on the emitting surface 232 of the window sheet 23, the light beam outside the preset wavelength range in the light beam homogenized by the light waveguide element 2 is filtered by the filtering film 3, and therefore, the light beam emitted through the emitting surface 232 of the window sheet 3 is the light beam with the preset wavelength homogenized by the light waveguide element 2 and filtered by the filtering film 3.
