SureLock™ 405 nm Wavelength Stabilized Laser Diode

Coherent’s SureLock™ 405 nm, 12 mW, 25 mW, and 40 mW Wavelength Stabilized Laser Diodes are miniature lasers in a collimated, cylindrical package. 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.
