laser with mixed yttrium and lanthanidsilicateneinkristallen.

摘要

The laser comprises a laser cavity (2) containing a single crystal (4) as light emitter, means (12, 14) for amplifying the light issuing from the single crystal, means for the exit (14) of the light out of the laser cavity and optical pumping means (6), characterised in that the single crystal has the following formula (I):… Y2-2x-2yM2xYb2ySiO5 (I in which M denotes a lanthanide chosen from erbium and thulium and x and y denote numbers such that 0x/=0.2 and 0/=y/=0.2. …IMAGE…
