Abstract
A novel electro-optically tuned external-cavity diode laser with volume Bragg grating (VBG) is proposed and demonstrated experimentally. A piece of high electro-optic coefficient Lead Lanthanum Zirconate Titanate (PLZT) transparent ceramic is inserted into the external cavity to act as a refractive index tunable component to change the cavity length. By adjusting the voltage applied to the PLZT, a single mode tuning range of 2.5G without mode hoping is achieved. The laser wavelength is around 810.0nm with the line-width of 19MHz and the SMSR of 37dB.
