[0020] The present invention will be further described below with reference to the drawings and embodiments.
[0021] Such as figure 1 As shown, a controllable photofluid dye laser based on the electrorheological effect includes a beam shaper 2, a spatial light modulator 3, a converging lens 4, and a photofluid component 8; the optical path of the incident pump beam 1 is sequentially arranged with beams Shaper 2, spatial light modulator 3, converging lens 4, optical fluid component 8. After the pump beam 1 is shaped by the beam shaper 2, it is modulated by the spatial light modulator 3, and then is focused by the converging lens 4, and the focal area Located inside the optical fluid component 8; the optical fluid component 8 is a cylindrical cavity structure, two end faces are respectively provided with a first reflector 10 and a second reflector 12 to form an optical resonant cavity, the optical fluid component 8 is provided inside There is a dye suspension 9. The cavity of the...
