Abstract

A miniaturized, standalone tunable semiconductor laser module operating at a wavelength of 633 nm with a footprint as small as 10 mm × 5 mm is presented. The module is based on an external cavity diode laser system with no moving parts and features a frequency tuning range of 25 GHz with a spectral linewidth of approximately 10 MHz. An output power of 10 mW within a nearly diffraction-limited beam is demonstrated. The electrical power consumption, including thermal management, is around 0.7 W.
