PURPOSE:To provide for a laser which allows a plurality of laser beams to be oscillated. CONSTITUTION:In a laser where a laser beam is oscillated by a solid laser medium 4 with an oscillation light of a semiconductor laser 1 as an excitation light, a drive control circuit 2 which is oscillated by time-sharing a plurality of semiconductor lasers 1 and these plurality of semiconductor lasers 1 simultaneously or at each specified timing and a solid laser beam all-reflection film 5 which reflects a solid laser beam excited by excitation light from the above each semiconductor laser 1 are provided. |
