Fiber-Coupled SureLock 785nm/830nm/1064nm Butterfly Raman Laser

SureLock™ 785 nm/830 nm/976 nm/ 1064 nm Butterfly Raman Lasers

Coherent’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 785 nm to 1064 nm.

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.

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