ATM / SHG

ATM SHG dye laser

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

  • Compact – rugged – efficient
  • Automated tuning
  • Integration in different applications
  • Can be pumped by different laser type

Setup

ATM stands for a series of automated tuning modules. They are compact, efficient and variable. The standard version of the ATM is optimized for LTBs MNL nitrogen laser series as pump lasers. In addition, excimer and Nd:YAG lasers (with pulse energies of up to 1 mJ) can be used as pump lasers.

Combined with the MNL nitrogen laser the ATM forms a laser system automatically tunable in the UV-VIS-NIR range and delivering subnanosecond pulses in the kilowatt range. To exploit the whole wavelength range from 225 – 950 nm, 15 standard dye cells are required. They are easily to exchange. An extensive cleaning and permanent renewing of the dye solution is not necessary. Both components, the nitrogen laser MNL and the ATM are controlled from a PC via a comfortable Windows software.

The compact laser system has only one beam output for the pump laser, the dye laser or the SHG (switchable). It can be equipped with a fibre coupling. The beam guidance and the control of the laser is carried out via an easy-to-use software. The laser can efficiently be coupled into a multi-mode quartz fibre. The ATM is equipped with an internal sensor for energy measuring and for the optimal phase matching of the SHG. A DLL interface provides for the integration of the ATM in different applications. The following settings can be chosen via the software:

  • 337 nm, direct beam output of the nitrogen laser
  • 400 – 950 nm, dye laser
  • 225 – 400 nm, dye laser and SHG 1
