Coherent’s 685 nm Wavelength Stabilized Laser Diode is a single mode, single frequency laser packaged in an ultra-compact TO-can footprint. The extremely narrow linewidth, broad temperature operating characteristics and low power consumption 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.
