OPTICALLY-PUMPED VERTICAL EXTERNAL CAVITY SURFACE EMITTING LASER
An optically-pumped vertical external cavity surface emitting laser is provided to enhance an optical output by increasing a volume of a periodic gain region that is a multi-quantum well activation region. A DBR mirror(120) is formed on a substrate(110). A second multi-quantum well activation region...

| Zusammenfassung: | An optically-pumped vertical external cavity surface emitting laser is provided to enhance an optical output by increasing a volume of a periodic gain region that is a multi-quantum well activation region. A DBR mirror(120) is formed on a substrate(110). A second multi-quantum well activation region(130) is formed on the DBR mirror. A first multi-quantum well activation region(140) is formed on the second multi-quantum well activation region. A capping layer(152) is formed on the first multi-quantum well activation region. A first optical pump(160) is used for irradiating a pump beam having a first wavelength range on a surface of the capping layer. A second optical pump(162) is used for irradiating a pump beam having a second wavelength range on the surface of the capping layer. An external cavity mirror(170) is installed at the outside opposite to the DBR mirror. |
