LASER Russian patent published in 1997 - IPC

FIELD: laser engineering. SUBSTANCE: laser has active medium, output and nontransparent mirrors. Parallel first and seventh reflecting faces of active medium are orthogonal to second and eight reflecting faces. Output mirror is placed in front of twelfth transmitting face provided between first reflecting face and first seating fillet. Nontransparent mirror is mounted in front of sixth transmitting face provided between seventh reflecting face and second seating fillet. Third and fourth heat-transfer faces are located in front of eleventh reflecting face; ninth and tenth heat-transfer faces are made in front of fifth reflecting face. Sixth and twelfth transmitting faces are parallel to third and ninth heat-transfer faces. Bases of first and seventh reflecting faces equal mx, those of second and eight ones, -(m+1)x, and of sixth and twelfth ones, , where m is integer number; x is common measure of bases of mentioned reflecting faces. Third and ninth faces are positioned at angle (180-2θ) to fourth and tenth faces and at angle (90-θ) to fifth and eleventh faces, where θ > arcsinn12; n₁₂ is relative index of active medium refraction. EFFECT: improved design. 1 dwg
