FIELD: quantum engineering. SUBSTANCE: laser has active material, input and nontransparent mirrors. First and seventh active-material reflecting faces 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 seat. Nontransparent mirror is placed in front of sixth transmitting face provided between seventh reflecting face and second seat. Third and fourth heat-transfer faces are placed in front of eleventh reflecting face; ninth and tenth heat- transfer faces are placed 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 eighth ones, (m+1)x, and of sixth and twelfth ones,, where m is integer number and x is common standard for bases of mentioned reflecting faces. Third and ninth faces are inclined through angle (180-2&thetas;) to fourth and tenth faces and through angle (90-&thetas;) to fifth and eleventh faces, where &thetas; > arcsinn, and nis relative refractive index of active material. In this way, electromagnetic wave with smaller sectional area will cross many times within cyclic run a volume equal to three ones of active material. EFFECT: improved power density of laser. 1 dwg |
