A device for monitoring the emission wavelength of a laser (10) includes a semiconductor slice or slab (14) having first (141) and second (142) opposed surfaces. The semiconductor slice (14) is exposed to the radiation at an angle such that a portion of said radiation impinges onto the ...
The device has parallel measurement paths with optical filters and power detectors and an evaluation device; the transmission characteristics of at least some filters vary over the wavelength range. The evaluation device positively selects laser beam wavelengths from the measurement signal of the path ...
