We demonstrated a mode-hop-free external cavity laser (ECL) design incorporating a semiconductor gain chip and a fiber Bragg grating (FBG) with enhanced thermal sensitivity. The compact ECL features a narrow linewidth of 35 kHz and a high linear thermal tuning velocity of 65 pm/°C (8.125 GHz/°C), which is six times higher than that of normal FBG-based ECLs.

A 785nm external cavity laser diode with volume Bragg grating (VBG) used in Raman spectroscopy was presented. In order to improve the performance of Raman signal, the line-width of Laser diode (LD) is narrowed by external cavity technology and VBG, and the beam is also shaped by aspheric lens and fast-axis-collimator.
