The SWL-7500 series lasers offer extremely narrow linewidths from an OEM-ready platform designed for stability and longevity. This new addition to our market-leading line of external-cavity diode lasers offers single longitudinal mode performance at a single, fixed wavelength. The user may choose the output wavelength anywhere within a specified wavelength range and the factory will build the laser at that precise wavelength. Long-term wavelength and power stability makes this laser a miniature work horse. With a footprint that is smaller than a business card, the laser will fit in most instrument designs with room to spare. We have carefully designed these lasers to operate continuously on a single longitudinal mode and minimal frequency drift as the heart of any imaging, metrology, or spectroscopic measurements.
