Coherent Innova 90 Plus Ion Laser System

  • Series V Plasma Tube for Longest Lifetime
  • SuperInvar Resonator for Superior Passive Stability
  • Single-Frequency Option for Narrow Linewidth and Long Coherence Length


The Innova 90 Plus Ion Laser System is an updated and improved performance version of the Innova 90. It provides high levels of performance, long-term reliability, multiple operating configurations, and is easy to use. It is an excellent choice for the scientist looking for a flexible and broadly applicable high power source of laser light in the visible and ultraviolet spectral regions.
< />br /> All Innova 90 Plus lasers incorporate Coherent’s Series V metal/ceramic plasma tube. With many thousands in operation, the metal/ceramic plasma tube is now the accepted standard for high power and stability, while simultaneously delivering the best available plasma tube lifetimes. The new Series V tube is Coherent’s latest version of metal/ceramic technology, which incorporates many improvements, primarily in gas-flow dynamics, to further extend the tube’s lifetime and performance.

The overall stability of an ion laser system primarily depends on a properly designed and implemented resonator. The Innova 90 Plus SuperInvar resonator structure provides exceptional stability, resistance to ambient thermal effects, and mechanical rigidity. The high thermal mass and high mechanical mass of the resonator, in combination with its kinematic mounting design, reduce the effects of environmental changes to a minimum. Thermal compensation of the wavelength selector further ensures long-term stable performance in single-line operation.

For stable single-frequency performance, the Innova 90 Plus uses a solid, temperature-stabilized etalon to ensure excellent frequency stability. Together with the SuperInvar resonator structure, the temperature- stabilized etalon allows independent adjustment of the tilt angle and the etalon transmission peak. This design, which results in high conversion efficiencies for both low-gain and high-gain lines, provides high output power with excellent frequency stability.

The Innova 90 Plus power supply is a fully regulated series passbank design, with proven performance now in the millions of hours. This design provides the lowest noise operation available—0.2% rms— in either light or current regulation mode.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
