ABSTRACT:
A solid-state laser crystal constituting a laser-diode-excited solid-state laser apparatus or an optical fiber constituting a fiber laser apparatus or fiber laser amplifier is doped with one of Ho3+, Sm3+, Eu3+, Dy3+, Er3+, and Tb3+so that a laser beam is emitted from the solid-state laser crystal or the optical fiber, or incident light of the fiber laser amplifier is amplified, by one of the transitions from5S2to5I7, from5S2to5I8, from4G5/2to6H5/2, from4G5/2to6H7/2, from4F3/2to6H11/2, from5D0to7F2, from4F9/2to6H13/2, from4F9/2to6H11/2, from4S3/2to4I15/2, from2H9/2to4I13/2, and from5D4to7F5. The above solid-state laser crystal or optical fiber is excited with a GaN-based compound laser diode.
