UDL SHG dye laser

Pulsed dye laser for manual UV-VUS-NIR tuning with frequency doubler SHG

  • Compact – rugged – efficient
  • Manual tuning  225 nm – 950 nm
  • Can be pumped by different laser types
  • Low cost


The UDL dye lasers are small and compact. They are characterized by a transversal pump geometry and depending on the model by different spectral bandwidths. Due to their modular design and their small size, they can optimally be adapted to the specific measuring process. Different wavelengths are generated with the UDL 100 by a simple exchange of the dye cells. The wavelength is adjusted by a micrometer screw.

The SHG frequency doubling units are modules for doubling the dye laser radiation. One SHG module is available that covers the wavelength range from 225-400 nm. The phase matching of the BBO crystal is realized via a micrometer screw. The manually tunable UDL and SHG modules are optimized for being pumped by the MNL nitrogen lasers. Here the dye lasers do not require a cooling or dye circulation systems. But excimer or Nd:YAG lasers with pulse energies of up to 1 mJ can also be used as pump lasers.

In combination with the nitrogen lasers of the MNL model series, laser systems are provided continuously tunable over a wide tuning range and easily to be operated. Together with the MNL 100 nitrogen laser a particularly small, compact and cost-efficient tunable system is at your disposal.
