The invention provides a laser module comprising a laser diode, a focusing lens group, a transmitting and reflecting mirror, a first focusing lens group, a second focusing lens group, a fluorescent powder layer and a scattering layer. Laser output by the laser diode forms an incident laser beam with a controllable beam size and divergence angle after passing through the focusing lens groups; the incident laser beam is split by the transmitting and reflecting mirror to become two beams, one of the two beams is focused onto the fluorescent powder layer through the first focusing lens group, and the other beam is focused onto the scattering layer through the second focusing lens group; and fluorescent light output from the fluorescent powder layer and laser reflected by the scattering layer are mixed to form final output light. Through a structure of a laser searchlight provided by the invention, emergent beams with different divergence angles can be conveniently and rapidly obtained. 本发明提供了种激光模组，包括激光二极管，调焦透镜组，透
