Tm-based lasers are direct sources of high-power radiation in 2- µm spectral region ( 3 F 4 → 3 H 6 transition of Tm 3+ ) with applications in medicine, high-resolution spectroscopy, and remote ...

We report on AlInGaN-based blue and green edge-emitting lasers designed for low-current operation and low power consumption. By properly optimizing cavity length and mirror coatings, threshold ...
