Sapphire SF NX
CW Free Space and Fiber Pigtailed
Single-Frequency Lasers
Sapphire SF NX is a series of compact CW visible single-frequency
lasers based on Coherent’s unique OPSL (Optically Pumped Semicon-
ductor Laser) technology. Sapphire SF NX lasers come with an ultra-
narrow linewidth of <1.5 MHz, a high quality diraction-limited beam
with excellent pointing stability, high power stability and low noise.
Sapphire lasers are manufactured in cleanrooms using Coherent’s
patented PermAlign™ technology for optimal aligning and solder-
bonding the optics. Sapphire SF NX lasers come with a exible inter-
face concept: Analog, RS-232 or USB – it is up the user to select the
appropriate communication channel.
Sapphire SF NX lasers are intended for applications that need narrow
and ultra-narrow linewidth light such as Raman spectroscopy, inter-
ferometry, holography, metrology, and inspection.
