The Toptica MTA pro combines up to two MTA TA pro amplified laser systems into a 19” sub-rack and seamlessly integrates into the T-RACK or other suitable 19” racks. The modular design also enables integration of MTA BoosTA pro amplifier only modules or DL/DFB pro laser modules. MTA pro integration of the latter may help to avoid an extra MDL pro and comes with additional features and options.

  • Up to two lasers in TA proBoosTA pro or DL/DFB pro configuration
  • Spectral coverage 369 .. 1770 nm with powers up to 2 W from PM fiber
  • Includes AutoAlign for coupling into tapered amplifier and output fibers
  • Low noise and drift, narrow linewidth
  • Digital control via DLC pro for best performance and convenience

Like all building blocks of TOPTICA’s Laser Rack Systems, the MTA pro is designed to clear optical tables and to stow away lasers into a 19" form factor. It is ideally suited for integration into TOPTICA Laser Rack Systems that allow researchers to focus on their experiment rather than on their laser system.

When operated in TOPTICA’s T-RACK, the MTA pro has the same optical specifications as a fiber-coupled TA pro system. On top of that, it always includes AutoAlign, a fully-automated push-button coupling optimization into the tapered amplifier and the optical output fibers. Moreover, MTA pro supports output power stabilization.

The MTA pro modular laser unit features a full-extension pull-out mechanism and dynamic cable management, both ensuring easy access to the laser modules. Moreover, it offers passive vibration isolation decoupling the lasers from the environment. The unit consumes a total of 4 Rack Units (RU) in height, including an extra 1 RU blanking front panel recommended for thermal isolation between laser units. Optical output is fiber-coupled allowing for flexible laser light delivery wherever required.

The MTA pro laser modules are controlled with TOPTICA’s DLC pro. Its digital architecture enables low-noise laser operation, intelligent locking functions and remote control via Ethernet.
