Laser Stabilization and Beam Combining
Apr 2006
Ondax Inc.Request Info
Ondax’s PowerLocker  is ideal for increasing the brightness of high-power laser diodes and locking their emission wavelength. The short external cavity enabled by the PowerLocker provides better mode selection than systems based on Littrow and Littman cavities. The PowerLocker  is a volume holographic glass grating that reflects a specified wavelength at a given reflectivity. It has a narrow linewidth of <0.1 nm and provides very low thermal dependence of lasers (0.01 nm/°C). The PowerLocker (US patent 5,691,989) can be used in applications including diode-pumped solid state lasers, raman spectroscopy, RGB sources, frequency doubling, gas sensing, bioinstrumentation, Rb lasers, lung imaging, lidar, beam combining, metrology, graphic arts (printing and digital imaging), photodynamic therapy and visible lasers.
