Impact Statement:
1. We presented a design of a single-frequency green InGaN external cavity diode laser (ECDL) with 40-mW output power and 10-MHz linewidth. To my knowledge, it is first to realize green ECDL. 2. We analyzed the output efficiency of the ECDL under different polarization directions and emitted light patterns. The laser spectrum under the different applied currents and temperatures were also investigated. we obtained the information of tuning range and linewidth with applied current.
Abstract:
We present a design of a single-frequency green InGaN external cavity diode laser (ECDL) with 40-mW output power and 10-MHz linewidth. The ECDL was mounted in the Littrow configuration, with an overall efficiency of approximately 52% and a tuning region of 8 nm. We analyzed the output efficiency of the ECDL under different polarization directions and emitted light patterns. We used a spectrometer to analyze the laser spectrum under the different applied currents and temperatures. Finally, we obtained the linewidth of the ECDL using a scanning Fabry-Perot interferometer and found that the linewidth varied with the wavelength.
