Laser oscillation in Cr²⁺:ZnS waveguide thin-film structures under electrical pumping with impact excitation mechanism

Laser oscillation in Cr²⁺:ZnS waveguide thin-film structures under electrical pumping with impact excitation mechanism

The laser oscillation at room temperature in Cr²⁺:ZnS waveguide thin-film structures under electrical pumping with the impact excitation mechanism was first discovered after improvement of some waveguide optical properties. However, lasing turned out to be unstable and ceases soon, which is accom...
