Abstract

Laser technology is maturing rapidly and is rinding applications in areas such as high resolution spectroscopy, medicine, optical telecoms, radar-lidar, metrology… Thus there is a strong interest to develop high quality laser operating in the continuous-wave (cw) regime at room temperature (RT) in the λ = 0.5 – 3μm range. A highly coherent high power tunable laser design can be achieved using an extended-cavity quantum-well (QW) semiconductor surface emitting laser in a stable optical cavity, so called External-cavity VCSELs (VeCSELs).
