Abstract
Optically pumped semiconductor vertical-external-cavity surface-emitting laser (VECSEL) potentially provides an innovative approach to low-cost frequency agile lasers engineered for specific applications in infrared and visible range. In this paper, we report on the development and demonstration of a multi-Watt highly strained InGaAs/ GaAs vertical-external- cavity surface-emitting laser (VECSEL), which can be tuned from 1147 nm to 1197 nm. Based on this tunable InGaAs/GaAs VECSEL and intracavity frequency doubling, we develop multi-Watt frequency-doubled tunable VECSEL in a wide yellow-orange band (579 ~595 nm). This compact high-power yellow-orange laser provides an innovative approach to an affordable guidestar laser (~589.1 nm) solution, and has a lot of important applications in biomedicine.
