| 摘要 |
The invention relates to a system for generating a laser beam via non-linear effects, comprising: a monofrequency continuous-wave laser source; and an external resonant cavity referred to as a microchip cavity. According to the invention, the microchip cavity is composite insofar as it is a unitary assembly of a plurality of materials comprising: at least one nonlinear crystal (5); an entrance mirror (4a); a concave mirror (6a) deposited on a material (6) fixed to the nonlinear crystal - the material on which the concave mirror is deposited is different from the constituent material of the nonlinear crystal; a first thermoelectric module (P2) for controlling the temperature of the nonlinear crystal; and at least one second thermoelectric module (P1) for controlling at least the temperature of the material on which the concave mirror is deposited. |
