Abstract
An electrically-pumped short wavelength vertical cavity surface emitting laser (VCSEL) is optically coupled to a long wavelength VCSEL for optically pumping the long wavelength VCSEL. The long wavelength VCSEL has a long wavelength active-absorber medium interposed between a top long wavelength mirror and a bottom long wavelength mirror. The long wavelength VCSEL emits radiation at a first wavelength in a range from 1250 nm to 1650 nm. The short wavelength VCSEL emits radiation at a second wavelength in a range from 700 nm to 1050 nm.

An optically-pumped long-wavelength laser, comprising:
- a long wavelength vertical cavity surface emitting laser (VCSEL), the long wavelength VCSEL having a long wavelength active-absorber medium interposed between a top long wavelength mirror and a bottom long wavelength mirror, the long wavelength VCSEL emitting radiation at a first wavelength in a range from 1250 nm to 1650 nm;
- and
- an electrically-pumped, short wavelength VCSEL optically coupled to the long wavelength VCSEL for optically pumping the long wavelength VCSEL, the short wavelength VCSEL emitting radiation at a second wavelength in a range from 700 nm to 1050 nm.
A method of stimulating emission in a long wavelength vertical cavity surface emitting laser (VCSEL) causing radiation at a first wavelength in a range from 1250 nm to 1650 nm to be emitted by the long wavelength VCSEL, comprising the following step:
- injecting radiation into the long wavelength VCSEL at a second wavelength in a range from 700 nm to 1050 nm with a short wavelength VCSEL, which is optically coupled to the long wavelength VCSEL.
