  • Abstract
    An external cavity laser transmitter module with only 20 mm cavity length is presented. A prism grating is used as a frequency-selective reflector. The coupling element between the laser diode and the prism grating is a permanently attached GRIN rod lens. Linewidths below 500 kHz at an output power of approximately 2mW have been reached with this compact set-up.
