| Abstract | We present a novel external cavity diode laser design devel- oped for applications in atomic physics that 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 the 87 Rb, 85 Rb rubidium D2 line absorption at 780 nm in an atomic optics test experiment. Our novel laser system design has a size of 28.7620.6512 mm. The wavelength can be tuned and swept from 780.2463 to 780.2379 nm equivalent to 4.14 GHz using piezoelectric transducer PZT actuators integrated on the silicon flexure. A frequency tuning range of 17.149 GHz can be obtained by changing the VHG tem- perature. The deflection of the silicon flexure is 129.19 nm. The advan- tage of combining a VHG and a silicon flexure is that the frequency can be coarsely tuned to 780.24 nm and swept at this center frequency with a range of 4.14 GHz by PZT. Moreover, the frequency fine tuning can be achieved by changing the VHG temperature to observe the rubidium spectrum. The laser output power is measured as 59 mW at 780.2474 nm. © 2008 Society of Photo-Optical Instrumentation Engineers. |
