808-nm Single-Mode Diodes
May 2008

For Solid-State Laser Pumping
GLASGOW, Scotland, May 14, 2008 -- Intense Ltd.'s 6020-808 series are high power, high brightness, 808-nm single-mode laser diodes for green laser pumping.

The 6020-808 series provide high beam quality with up to 200 mW of output power and high brightness with low astigmatism and a Gaussian far field. Designed for pumping solid-state laser sources, the new diodes allow OEMs to directly couple the output of the diode to the crystal, Intense said.

The lasers can be used as in a variety of solid-state pumping applications, including vanadate, YLF (yttrium lanthanum fluoride), and Nd:YAG.

IntenseDiodes.jpgPart of Intense's 6000 series of single-mode lasers, the  6020-808 diodes are based on the company's quantum-well intermixing (QWI) technology, which increases the brightness and reliability of laser diodes while avoiding the usual problems associated with catastrophic optical mirror damage, Intense said. The diodes offer high electrical conversion efficiency in a range of operating temperatures, from 25 to 50 °C. The lasers are available in a selection of free-space packages, including 9 mm, C-mount, and TO3. Custom packaging and wavelengths are available on request.

"The series 6020-808 single-mode laser pumps provide OEMs with the optical tools they need to develop products with lower costs, higher efficiencies, and longer lifetimes," said Kevin Laughlin, VP HPL Global Business Development at Intense. "The series 6020 allows OEMs to design products with powerful yet significantly less complex optical systems. Reduced component counts mean lower system costs. These QWI-enabled series 6020 also provide higher conversion efficiencies and longer lifetimes, especially when compared to higher power multimode devices."

The high power, efficiency, and operating temperatures of the diodes have attracted a high level of interest from solid-state laser source producers, most recently from those pumping vanadate, Intense said. Vanadate is used to design green lasers, a key component in the manufacture of RGB display sources, handheld picoprojectors, scientific instruments including interferometers, and precision machining. Diode-pumped green lasers are also used for targeting in defense applications and for spectroscopic applications in the medical industry.

The 6020-808 series single-mode laser diodes are also available in custom packaging to match OEM system requirements; OEM discounts are based on quantities ordered.

A two-electrode device with an anode and a cathode that passes current in only one direction. It may be designed as an electron tube or as a semiconductor device.
An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light. Interferometers are used extensively for testing optical elements during manufacture. Typical designs include the Michelson, Twyman-Green and Fizeau interferometers. The basic interferometer components are a light source, a beamsplitter, a reference...
