DL pro
Tunable diode laser with digital control DLC pro
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
Our 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.
See TOPSeller section below for details. For additional wavelengths, please refer to our laser diode stock lists: AR-coated and Fabry-Perot laser diodes.

Options
Narrow linewidth
With this option DL pro laser systems are optimized for narrow linewidths. It is also suited for seed lasers of TA or NLO systems but not for DL pro HP lasers.
Fiber Coupling (FiberDock)
TOPTICA’s patented fiber coupler provides highest single-mode fiber-coupling efficiencies, easy alignment and at the same time highest stability. TOPTICA additionally offers a wide range of single-mode and polarization-maintaining fibers, including fiber-optic beam splitters. Optical isolation is mandatory for fiber-coupled diode laser systems.
Optical Isolation
Isolators are used to protect the laser diode against back reflections. This not only prevents damage to the diode but also ensures untroubled tuning and single-frequency operation. Fiber-coupling with angle-polished fibers (both ends) requires at least a single-stage isolator (> 30 dB). Double-stage isolators are needed if reflections from the experiment into the laser are expected. Fiber-coupling with non-angle-polished fibers also requires a double-stage isolator (> 60 dB).
Beam Shaping
To shape elliptical laser beams into round profiles, either an anamorphic prism pair (APP) or cylindrical lenses are used. The compressed circular beam is small enough for using inexpensive small-aperture isolators, and the fiber-coupling efficiency is enhanced by approximately 10 %. The compression ratio is set at the factory.
Motorization
The motorization of the coarse tuning offers manual control and operation via software interface. This option is available for most DL pro laser systems (most AR laser diodes and some FP diodes) including DL pro HP laser systems.
Bias-T
The DL pro (HP) has two modulation inputs that allow current modulation frequencies of up to 150 MHz. A Bias-T allows even higher current modulation frequencies of up to several GHz, depending on the diode. It is also suited for seed lasers of TA or NLO systems.
Electronics Modules
A broad variety of electronic locking modules is available for frequency stabilization.
