PCT No. PCT/SE95/00833 Sec. 371 Date Jan. 3, 1997 Sec. 102(e) Date Jan. 3, 1997 PCT Filed Jul. 6, 1995 PCT Pub. No. WO96/01511 PCT Pub. Date Jan. 18, 1996The present invention relates to a resonator for at least two laser modes from an optically pumped laser medium, in which each laser mode is reflected between a highly-reflective mirror and an output mirror. The laser resonator feeds back and separates at least two longitudinal laser modes having a given stable frequency difference between the modes by the laser medium being adapted to emit the concerned number of laser modes which are arranged to pass a Fabry-P+E,acu e+EE rot etalon at different angles.
