Abstract
A tunable external cavity diode laser (ECDL) system with narrow line-width emission at 410Â nm is presented. Based on a commercially available laser diode and a Littrow arranged reflective holographic grating, a maximum output power over 500Â mW with line-width of about 50Â pm is achieved at the rated current. The power efficiency is over 85% and the threshold decreases over 20% compared to the free-running laser diode. Manual tuning range over 5Â nm is achieved around threshold condition and over 2Â nm at high injection currents up to 500Â mA with side mode suppression ratio larger than 20Â dB.
