Laser Lines Ltd. has released a true fiber-pigtailed option for Cobolt AB's 04-01 series single-longitudinal-mode lasers. In the compact and robust fiber delivery option, the single-mode polarization-maintaining fiber is fixed inside the hermetically sealed package using proprietary HTCure technology, resulting in a permanently aligned, true fiber-pigtailed laser with stable output power. The Cobolt 04-01 devices are continuous-wave diode-pumped solid-state lasers. The ultraviolet and visible models have a narrow spectral bandwidth and produce a high-quality beam over a wide range of operating temperatures. The lasers are based on proprietary periodically poled potassium titanyl phosphate technology, which provides improved power efficiency, wavelength flexibility and multiline emission capability. Features include CW power up to 300 mW and low noise of <0.25% rms.
