Wavelength Stabilized Benchtop Laser for Raman

Coherent’s new Mini-Benchtop Lasers are a low-cost, high performance design alternative to existing benchtop lasers for Raman spectroscopy. Ultra-compact and easy to use, the Mini-Benchtop laser incorporates a Surelock™ VHG-stabilized laser diode to deliver steady, high-power, spectrum-narrowed performance. Offering plug-and-play operation with fiber-optic probes via a front-panel FC/PC fiber connector, the Mini-Benchtop laser includes manual power controls, a touchscreen display, and emergency stop, delivering better than 1% power stability and less than 1-minute warm-up.

All SureLock Series lasers are stabilized using the 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.

Comes with an FC/PC front panel connector and optional 105 mm 3-meter fiber cable with FC/PC or SMA end connector. Available in powers up to 500 mW at 785 nm, 830 nm, 976 nm and 1064 nm.
