LASER WITH COMPLEX CORE Russian patent published in 1996 - IPC

FIELD: quantum electronics. SUBSTANCE: laser has open cavity 1, excitation source 2, solid core which is designed as rectangular parallel-plate chip 3, which is made from stimulating material which is optically connected to films 4, which depth is λ/4 where l is wave length of laser. Films are connected to prisms 5. Refraction index of chip equals to those of prisms, while refraction index of film is lesser than those of chip and prisms. Excitation source is located at angle that provides following condition sinΦ≥n₁/n, where Φ is inclination angle of flat monochrome wave (excitation light), n₁ is refraction index of films, n is refraction index of prisms. EFFECT: increased functional capabilities. 1 dwg
