Abstract：
 The invention belongs to laser amplifier and laser cavity field, and comprises exactly: two curved reflectors set opposite and obliquely to form non-telescopic non-confocal structure, the laser gain medium arranged between last two mirrors, and an optional cavity mirror away the light path. Wherein, the laser beam arrives the reflectors to multiple reflect and form a folded light path after passing the gain medium for many times, the beam normal arrives one reflector and is reflected to return along original path or, the beam oblique arrive at reflector, and passes medium only one time. This invention simplifies structure, and has well resistance to error or disturbance.
