Recent progress in diamond growth via chemical vapor deposition (CVD) has enabled the manufacture of single crystal samples sufficient size and quality for realizing Raman laser devices. Here we report an external cavity CVD-diamond pumped by a Q-switched 532 nm laser. In investigated configuration, dominant output coupling was reflection loss at diamond's uncoated Brewster angle facets caused crystal's inherent birefringence. Output pulses wavelength 573 with combined energy 0.3 mJ were obtained slope efficiency conversion up to 22%.
