摘要 |
The present invention relates to a laser source for the infrared wavelength range which comprises a pump laser (1) which emits radiation (PP) which is input radiation to a first optical parametric oscillator (3, 4, 5), whose output radiation (SP) is input radiation to a second step in the form of a second optical parametric oscillator (7, 8, 9) or an optical parametric generator. At least one of the reflective devices of the first optical parametric oscillator consist of a Bragg grating (5) in a bulk material. |
