We have developed a fast multi-wavelengths switching laser platform. The tuning mechanism is based on a micro-mirror array DLP chip from a commercial pico-projector forming the end mirror of an external cavity laser diode. We report progress on a working prototype of a single frequency laser with a wavelength that is switchable between any five wavelengths spanning 765 nm to 783 nm. Switching time between any two wavelengths is equal to the switching time of the DLP micro-mirrors… CONTINUE READING
