Abstract:
(EN) A frequency-doubling laser and a harmonic laser light generating method; the frequency-doubling laser comprises a first reflecting mirror (1), a second reflecting mirror (2), a gain medium (3), a telescope module (5), a polarizing element (6) and a nonlinear crystal (7); the first reflecting mirror (1) and the second reflecting mirror (2) are provided at an interval to form a resonant cavity of the frequency-doubling laser; the polarizing element (6), the gain medium (3), the telescope module (5) and the nonlinear crystal (7) are disposed in the resonant cavity, the telescope module (5) being disposed between the gain medium (3) and the nonlinear crystal (7). The frequency-doubling laser and the harmonic laser light generating method broaden the placement position of the nonlinear crystal (7), and reduce the probability of damage to the nonlinear crystal (7).
(FR) L'invention concerne un laser à doublage de fréquence et un procédé de génération de lumière laser harmonique ; le laser à doublage de fréquence comprenant un premier miroir réfléchissant (1), un second miroir réfléchissant (2), un milieu de gain (3), un module de télescope (5), un élément de polarisation (6) et un cristal non linéaire (7) ; le premier miroir de réflexion (1) et le second miroir de réflexion (2) sont disposés à un intervalle pour former une cavité résonante du laser à doublage de fréquence ; l'élément de polarisation (6), le milieu de gain (3), le module de télescope (5) et le cristal non linéaire (7) sont disposés dans la cavité résonante, le module de télescope (5) étant disposé entre le milieu de gain (3) et le cristal non linéaire (7). Le laser à doublage de fréquence et le procédé de génération de lumière laser harmonique élargissent la position de placement du cristal non linéaire (7), et réduisent la probabilité de détérioration du cristal non linéaire (7).
(ZH) 一种倍频激光器及谐波激光产生方法,倍频激光器包括第一反射镜(1)、第二反射镜(2)、增益介质(3)、望远镜模块(5)、偏振元件(6)以及非线性晶体(7),第一反射镜(1)及第二反射镜(2)间隔设置形成倍频激光器的谐振腔,偏振元件(6)、增益介质(3)、望远镜模块(5)以及非线性晶体(7)设置于谐振腔中,且望远镜模块(5)设置于增益介质(3)与非线性晶体(7)之间。倍频激光器及谐波激光产生方法放宽了非线性晶体(7)的放置位置,减少了非线性晶体(7)的损伤几率。
