An overall tunability extending from 1790 to 2042 nm is achieved with maximum output powers of 400 mW for an absorbed pump power of 1 W. Various doping levels, pump wavelengths and polarization configurations are compared and the advantages of the monoclinic double tungstates over other Tm-hosts are outlined.8 p.application/pdfeng(c) IEEE, 2004LàsersGadolinium compoundsLaser transitionsLaser tuningOptical materialsOptical pumpingPotassium compoundsSolid lasersThuliuminfo:eu-repo/semantics/article543114info:eu-repo/semantics/openAccess
