Product Details

The tunable dye laser is an important component in many optical systems for combustion diagnostics.  The tunable dye laser, generally pumped by a Nd:YAG laser source with frequency doubling and tripling units, provides a wide range of wavelengths from UV to IR.  The dye laser is easily expandable, allowing measurements of additional species.  Its modularity and flexibility provide easy access to a wide range of different radicals, such as CO, OH, NO, CO 2 , and CH, for example.  In addition, its high spectral resolution allows for high species selectivity.

 SPECIFICATIONS

Tunable Dye Laser Specifications table

Much of the scientific work with dye lasers is done in the ultraviolet. The UV extension on the laser bench provides better mechanical stability and compactness. It is a modular frequency doubling and mixing system, consisting of two mechanical rotating supports for crystals and related fused silica compensators, the infrared delay line (mixing) and the optional automatic tracking system.

360-420nm spectral range: achieved by mixing the fundamental frequency of the dye laser with the residual infrared from the Nd:YAG laser. Even if the 380-420nm range is directly reachable with 355nm pumped dye, the mixing process using a 532nm pumped dye gives better results.

277-360nm spectral range: achieved by doubling the fundamental frequency of the dye laser.

217-277nm spectral range: achieved by mixing the frequency doubled output of the dye laser with the residual infrared from the Nd:YAG laser.

200-217nm spectral range: achieved by tripling the fundamental frequency of the dye laser.
