Toptica DL Pro: Tunable diode laser with digital control DLC pro


Toptica's DL pro is the ultimate tunable diode laser. Its revolutionary mechanical design allows for both easy operation and extreme stability at the same time. It offers highest output powers, and optimized mode-hop-free tuning with a perfectly positioned virtual pivot point for the grating movement (Patents: DE 10 2007 028 499 and US 7970024). Together with the digital control DLC pro controller it shows unrivalled linewidth and drift – with the most comfortable and intuitive user interface. Also available with the economic SYST laser electronics. A software license may be purchased to enable frequency-locking features.

The DL pro HP diode laser features a special resonator design, which allows for higher single-mode output powers from "visible" laser diodes. Like the DL pro, it is an extended cavity diode laser (ECDL). Both lasers feature various modulation inputs and may be equipped with various options like fiber coupling, beam shaping etc. The lasers may also be driven by the economic Sys DC 110 laser control, however we highly recommend the DLC pro due the superior performance, especially for the DL pro HP lasers.

The DL pro is available with all laser diodes listed in our stocklist of AR-coated and Fabry-Perot laser diodes. An overview of the resulting wavelength coverage is shown in the Additional Information below.

We provide a number of TOPSellers representing direct solutions for typical applications such as laser cooling of atoms or ions. These systems combine a DLC pro and either a DL pro or DL pro HP including an appropriate isolator. They may be combined with fiber coupling and the software license.

DLC DL pro TOPSellers are available at these wavelengths: 
850, 780, 670, 633 nm.

DLC DL pro HP TOPSellers are available at these wavelengths: 
637, 461, 420, 399, 397, 369 nm.

  • Tunable diode laser in patented pro design
  • Ultra-stable against temperatures & acoustics
  • With digital control DLC pro: Less drift & linewidth
  • Linewidth down to 10 kHz free running
  • Linewidth below 1 Hz possible with lock to external reference cavity
