The new Integral lasers offer extremely narrow linewidths on
an OEM-ready platform designed for stability and longevity. This
latest 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 will make this laser a miniature work
horse. With a footprint that is smaller than a business card, the
Integral lasers will fit in most instrument designs with room to
spare. We have carefully designed the Integral lasers to operate
continuously on a single longitudinal mode without mode hops
and minimal frequency drift as the heart of any imaging, metrology,
or spectroscopic measurements.
