SureLock 785/830/976/1064nm Butterfly OEM Laser Module

SureLock™ 785/830/976/1064 nm Butterfly OEM Laser Module

Coherent’s OEM Butterfly Laser Module is a wavelength-stabilized, high-power, compact fiber-coupled laser platform designed specifically for incorporation into Raman spectroscopy or other analytical instrumentation systems. The ultra-compact electronics provide constant temperature control, along with variable analog current control and an interlock connection to simplify integration. An included base plate allows for mounting in virtually any orientation.

All SureLock™ Series lasers are stabilized using the Coherent PowerLocker® Volume Holographic Grating (VHG), ensuring precise, ultra-stable center wavelengths, low temperature dependence, and consistent optical performance over the locked region. The narrowed linewidth, low power consumption, and broad stabilized temperature operating characteristics deliver affordable, portable instrument-quality performance.

Available in 785 nm, 830 nm, 976 nm, and 1064 nm versions with power levels up to 600 mW. Comes with an FC/PC connector.
