Abstract
The invention relates to a radiation source unit for supplying shortwave optical radiation, and to a method of assembling such a unit. The radiation source unit comprises a diode laser and a waveguide of a non-linear optical material for converting the diode laser radiation into radiation having a smaller wavelength. The diode laser is provided in a bush having a first end and a second, open end. The second end is adapted to accommodate a first holder in which a lens system is arranged for imaging the exit plane of the diode laser on the entrance plane of the waveguide. At a side of the first holder remote from the diode laser a second holder is secured in which the waveguide is arranged. Said holders are aligned and fixed with respect to each other in such a way that the chief ray of the diode laser beam, the optical axis of the lens system and the axis of the waveguide are in alignment, and that the diode laser beam is focused on the entrance aperture of the waveguide.
