Feedback-Dependent Threshold of Electrically Pumped VECSELs
نویسنده
چکیده
We present the investigation of the feedback-dependent threshold of an 822 nm wavelength electrically pumped vertical-external-cavity surface-emitting laser (VECSEL). The setup is capable of resolving micrometer-size features on the laser surface, while demanding highly accurate alignment. Modified design criteria are developed, which address this issue, and approaches for the fabrication of miniaturzied devices are outlined.

Blue Light Emitting Electrically Pumped VECSELs with Optical Powers in the Milliwatt Range
In the last few years, VECSELs have become an attractive laser source for various applications. Due to favorable features, such as high output power and good beam quality, optically pumped semiconductor VECSELs (OPS-VECSELs) [1] can be used, e.g., in laser printing, absorption spectroscopy or as a pump laser in the near-infrared spectral range. Furthermore, the extended cavity configuration giv...
متن کاملCavity Optimization of Electrically Pumped VECSELs
Surface-emitting lasers with an external cavity delivering a diffraction-limited beam have shown the potential to outperform edge-emitting devices in applications demanding high brightness (emitted intensity per unit solid angle), like pumping of doped fiber amplifiers or frequency doubling [1]–[3]. Due to the large mode size, the VECSEL concept is powerscalable by expanding the pumped area and...
متن کاملA Fabrication Approach for Hybrid-Integrated Electrically Pumped VECSELs
Unlike a vertical-cavity surface-emitting laser (VCSEL), which comprises two highly reflecting distributed Bragg reflectors (DBRs), the extended cavity in VECSELs employs a third mirror. The fabrication of such a device requires a long process chain, including the patterning of the VCSEL structures, definition of the extended optical resonator, mirror coating and die bonding. While VCSELs have ...
