SureLock™ 785 nm Wavelength Stabilized Laser Diode

Coherent’s 785 nm 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 Coherent PowerLocker® Volume Holographic Grating, ensuring precise, ultra-stable center wavelengths, low temperature dependence and consistent optical performance over the locked region.
