Quantel expands capability of EverGreen laser for PIV / LIF research

Smallest PIV Laser on the Market Adds 266 nm Capability

Quantel Laser today announced the release of the EverGreen 266 nm laser designed for combined PIV and LIF experiments.

San Francisco, CA – Quantel Laser, a leader in the design and manufacture of high-power, solid-state lasers for Scientific, Industrial, Military and Medical applications, today announced the release of the EverGreen 266 nm laser designed for combined PIV and LIF experiments.  The EverGreen, a staple of Quantel’s compact and rugged “Big Sky Laser” product line, was first introduced in 2010 and quickly became the laser of choice for Particle Image Velocimetry (PIV).  This extension to the popular product line enables users to image in the UV, facilitating precise measurements of velocity and density fields for certain combustion experiments difficult to accurately measure with traditional techniques. 

Particle Image Velocimetry (PIV) is an imaging technique used to study flow in aerodynamics and fluid mechanics.  It utilizes lasers to measure velocity fields by taking two images very close together in time and calculating flow by observing particle movement within the velocity field.  PIV is typically performed with pulsed nanosecond 532 nm lasers such as Quantel’s EverGreen and Twins product lines. However, researchers are increasingly looking at different, more subtle effects that are best imaged via UV excitation since organic molecules in the flow have broad absorption around 266 nm and emit in the visible allowing the use of standard PIV cameras. 

 Quantel’s EverGreen 266 will be showcased at the Photonics West conference in San Francisco from Feb 10-12.

 “The EverGreen has been particularly popular for this application due to its small size, reliability, versatility and ease of use,” commented Thomas Kraft, Product Line Manager.  “We retained those features with this new release and added the capability of accessing the 266 nm wavelength with a simple command accessible via computer or remote box.  Users can thus easily switch between 532 nm and 266 nm, increasing the versatility and flexibility of their laser.”

“The Big Sky Laser product line has always been synonymous with compact, rugged reliability,” said Gregory Smolka, VP, Sales & Marketing.  “The EverGreen has been so popular for this application because it’s a simple plug-and-play tool that just works.  We’re pleased to be able to support our customers with this new capability.”

 Key features

  • 30 mJ of 266 nm per pulse
  • Double pulse operation at 15 Hz
  • Simple, hands-off switching between 532 nm and 266 nm
  • Compact, Rugged Laser Head – ½ the size of comparable systems
In addition to the EverGreen 266, Quantel Laser also offers high power, pulsed nanosecond lasers, fiber lasers, laser diode stacks and custom laser solutions.
