Whether you need the flexibility of multiple wavelengths from a single laser, the stability inherent in an atomic transition, or the confidence that comes from keeping an established process, there are many reasons for selecting a Spectra-Physics gas laser for your research or equipment manufacturing needs. Be it a water-cooled ion laser for high power visible or UV, an air-cooled ion laser for lower power visible, a nitrogen laser for nanosecond UV pulses, or helium-neon red and green lasers, Spectra-Physics gas lasers have been the right choice for longer than anyone else has been in the business.
