MEMS tunable Littman-Metcalf diode laser at 2.2 mu m for rapid broadband spectroscopy in aqueous solutions
We demonstrate a rapidly (3 ms) and widely (222 nm) tunable, compact external cavity GaSb-based diode laser with a HEMS mirror. It delivers from 8 to 24 mW power over the tuning range, showing the side-mode suppression ratio of >50dB and controllable mode-hops of similar to 18GHz.
