We present a novel external cavity diode laser design developed for atomic physics which employs a micromachined silicon flexure to sweep the laser frequency and a volume holographic reflection grating (VHG) to provide the optical feedback. The advantages of using a silicon flexure are its simple microfabrication process and reduction of the overall size of the laser system. The results demonstrate an optimized threshold current reduction from 59mA to 43mA, a frequency sweeping range of 2.069 GHz, and 87Rb, 85Rb (Rubidium) D2 line absorption at 780 nm.

In this paper, a widely tunable external cavity diode laser (ECDL) with an ultra-high side mode suppression ratio (SMSR) was fabricated. Three configurations were constructed to investigate the relationship between the grating features and the SMSR. When a 1200 grooves/mm grating with a first order diffraction efficiency of 91% is utilized in the external-cavity laser system, a maximum SMSR of 65 dB can be achieved. In addition, the tunable range reaches 209.9 nm. The results show that the laser performance can be improved by proper high grating groove number and first-order diffraction efficiency.
