DOI: 10.1016/j.ijleo.2021.167005

Abstract: Abstract The causes and suppression methods of parasitic lasing in transverse direction of Fe2+:ZnSe laser are analyzed theoretically and experimentally. For a crystal with given diameter, there exists a maximum pump spot diameter dmax, below… read more here.

DOI: 10.1364/ol.384300

Abstract: We report, for the first time, to the best of our knowledge, a femtosecond mode-locked Fe:ZnSe laser. Passive mode locking is implemented using graphene as a saturable absorber. The laser operates at 4.4 µm with… read more here.

DOI: 10.1364/ol.43.000623

Abstract: The characteristics of an Fe:ZnSe laser thermoelectrically cooled to 220 K are described. Output energy of 7.5 J and optical-to-optical efficiency of 30% have been demonstrated in single-shot operation at 4.3 μm with a 2.94 μm Er:YAG pump laser.… read more here.
