85 W VECSEL output at 1270 nm with conversion efficiency of 59 %

Elyahou Kapon, Alexandru Mereuta, Alexei Sirbu, Vladimir Iakovlev, Andrei Caliman

We report on 1270 nm vertical-external-cavity surface-emitting lasers (VECSELs) with up to 59% conversion efficiency and maximum output power of 8.5 W (pump limited), at 5 degrees C heat sink temperature. These VECSELs comprised wafer-fused gain mirrors in ...

Laser a cavite verticale et a emission par surface

Elyahou Kapon, Alok Rudra, Alexei Sirbu, Vladimir Iakovlev

A tunable Fabry-Perot vertical cavity photonic device and a method of its fabrication are presented. The device comprises top and bottom semiconductor DBR stacks and a tunable air-gap cavity therebetween. The air-gap cavity is formed within a recess in a s ...

Transverse mode discrimination in long-wavelength wafer-fused vertical-cavity surface-emitting lasers by intra-cavity patterning

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Alexei Sirbu, Vladimir Iakovlev, Andrei Caliman, Pascal Gallo, Zlatko Mickovic, Nicolas Volet, Lukas Mutter

Transverse mode discrimination is demonstrated in long-wavelength wafer-fused vertical-cavity surface-emitting lasers using ring-shaped air gap patterns at the fused interface between the cavity and the top distributed Bragg reflector. A significant number ...
