SureLock™ 785nm Wavelength Stabilized Laser Diode

Ondax’s 785nm High-Power Wavelength Stabilized Laser is a high-power,single frequency, collimated laser packaged in an ultra-compact, TO-can footprint. The narrowed linewidth, low power consumption, and broad temperature operating characteristics deliver affordable, portable instrument-quality performance for a broad range of instrumentation applications. All SureLock™ Series lasers are stabilized using the Ondax PowerLocker® Volume Holographic Grating (VHG), ensuring precise, ultra-stable center wavelengths, low temperature dependence and consistent optical performance over the locked region.
