Coherent’s 633 nm High-Power Wavelength Stabilized Laser is a high-power, single frequency, collimated laser packaged in an ultra-compact, TO-can footprint, designed for HeNe replacement applications. The high operating power, narrowed linewidth, low power consumption, and broad temperature operating characteristics make it ideal for next-generation interferometer and analytical instrument designs, with 10x the power and 1/100th the size of a comparable HeNe laser. 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.
