SureLock™ 785nm-1064nm Butterfly Lasers for Raman

Ondax’s fiber-coupled and free-space butterfly lasers are designed specifically for Raman spectroscopy applications, and offer high-power, wavelength-stabilized performance in both fiber-coupled (FC) and free space (FS) configurations.  The narrowed linewidth, low power consumption, and broad stabilized temperature operating characteristics deliver affordable, portable instrument-quality performance in a broad choice of wavelengths from 785nm to 1064nm..

All SureLock™ Series lasers are stabilized using the Ondax PowerLocker® Volume Holographic Grating, ensuring precise, ultra-stable center wavelengths, low temperature dependence, and consistent optical performance over the locked region.

Fiber-coupled versions are available with FC/PC or FC/APC connectors.
