Solid state laser with superbroadband or control generation spectrum

We report here on a novel Color Center Laser (CCL) optical construction, providing two unique regimes of generation: (a) a simultaneous generation across the whole emission region of the LiF:F2- active medium (1.1-1.24 micrometers ) with efficiency of 15% and a simultaneous frequency doubling in the visible green-red spectral region (0.55-0.62 micrometers ); (b) a regime of multi frequency lasing with a special preassigned spectral distribution or spectral coding by means of placing a special mask or image controller into the pump beam.
