COOLING DEVICE FOR AN OPTICAL CRYSTAL OR LASER CRYSTAL |
摘要 |
The present invention relates to a cooling device (7) comprising Peltier elements (18) and mainly intended for cooling an optical crystal or a laser crystal (5) which is submitted to a high temperature stress and is used for generating laser beams (2), principally laser pulses. This device can for example be used for cooling the laser crystal of an optical amplifier or oscillator. In order to provide an efficient cooling while avoiding burning the crystal, said crystal (5) is arranged together with the Peltier elements (18) for cooling the same in an encapsulated container (8), the inner volume of which is maintained under vacuum and/or kept dry using a desiccating substance. Said crystal comprises at least one Brewster's window (32, 33) allowing the passage of the laser beams (2), wherein said window is arranged at an angle corresponding to the Brewster angle relative to the optical axis. |
