Patent number: 10505331Abstract: A CO2 laser that generates laser-radiation in just one emission band of a CO2 gas-mixture has resonator mirrors that form an unstable resonator and at least one spectrally-selective element located on the optical axis of the resonator. The spectrally-selective element may be in the form of one or more protruding or recessed surfaces. Spectral-selectivity is enhanced by forming a stable resonator along the optical axis that includes the spectrally-selective element. The CO2 laser is tunable between emission bands by translating the spectrally-selective element along the optical axis.Type: GrantFiled: September 6, 2017Date of Patent: December 10, 2019Assignee: Rofin-Sinar Laser GmbHInventors: Peter Rosenthal, Jens Schüttler, Florian Engel, Gongxue Hua
