Abstract: A laser hair removal handle has: a water supply block, a hollow metal structural member, and a fast axis collimating lens. A laser is mounted at a transverse edge of the L-shaped water supply block, and the hollow metal structural member is mounted at a vertical edge of the L-shaped water supply block, so that diffuse reflection light formed after a laser irradiates the skin enters a cavity of the hollow metal structural member. Since the hollow metal structural member is made of a metal material, the energy of the diffuse reflection light is effectively absorbed, and the effect of the diffuse reflection light on the emitted laser is reduced. The laser emitted by the laser is collimated by using the fast axis collimating lens. Compared with an optical waveguide in the prior art, energy loss is lowered.
