The proven laser solution for quantum applications
DL pro
Narrow linewidth, tunable diode laser
The DL pro was built for real-world quantum technology, where stability matters and downtime is not an option. As one of TOPTICA’s proven tunable external cavity diode lasers (ECDL), it supports everything from advanced research setups to industrial quantum systems and delivers reliably day after day. Its unique design covers almost every wavelength between 369 nm and 1770 nm, with up to 400 mW output power and free-running linewidths down to 0.6 kHz.
Thousands of DL pro systems are already powering quantum applications worldwide, from cooling and controlling atoms and ions to next-generation quantum computers. As one of the most trusted narrow linewidth lasers in its class, the DL pro combines excellent spectral performance with usability. A fully digital controller ensures stable operation, while the intuitive GUI makes remote access simple and convenient, especially in rack configurations.
And because no laser likes to work alone, the DL pro fits seamlessly into the extensive TOPTICA universe of driving electronics, software, and accessories. Plug it in, connect your setup, and let the physics happen.

Applications
Quantum physics science
TOPTICA's products are widely and successfully used for scientific applications in fundamental quantum technology. In these fields quantum physics, quantum optics, atom optics, photonics, statistical physics and related fields are investigated in order to understand the basics of quantum technology.
Quantum computing & simulation
Lasers are used to realize most of the quantum systems used for quantum computing and simulation. Lasers are utilized to prepare quantum states, to realize quantum gates, and to read out qubits. In addition, lasers are used to link different quantum systems (e.g. to connect quantum computers or quantum computing subunits), a major task of quantum communication. Tunable diode lasers, fiber amplifiers, optical frequency combs, and wavelength meters, ideally combined in laser rack systems as complete solutions, are the most important products.
Optical quantum clocks
Welcome to the next generation of time and frequency metrology. Harnessing the full power of quantum physics and ultra-stable lasers, optical quantum clocks are redefining how we measure time...
Quantum dots & microcavities
Highest stability and absolute frequency accuracy for inspecting PICs, semicon and RF devices. Expandable to high scan speed and broadest coverage.
Options
Single stage optical isolation
Protects the laser diode from back reflections to prevent damage but also to ensure untroubled single-mode operation and tuning. Also for fiber coupling with angle polished fibers (both ends) a single stage isolator is required.
Dual stage optical isolation
If reflections from the experiment into the laser are expected go for this high isolation option. Also for fiber coupling with non-angle polished fibers a double stage isolator is required.
Fiber delivery
Fiber Delivery (FD) is optionally available with TOPTICA's patented fiber coupler FiberDock and a suitable polarization maintaining (PM) fiber.
Motorization
Control coarse tuning via software interface. Available for most DL pro configurations, with most AR laser diodes and some FP diodes. Not available for DL pro F systems.
Bias-T
Allows current modulation frequencies above 150 MHz and up to several GHz, depending on the diode. Also suited for seed lasers of TA or NLO systems. Compatible with DL pro and DL pro HP, not with DL pro F.
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 as well as lasers of Laser Rack Systems but not for DL pro HP lasers. DL pro F lasers are always optimized for a narrow linewidth.
Beam shaping
To shape elliptical laser beams into round profiles, either an anamorphic prism pair (APP) or cylindrical lenses are used. The compression ratio is set at the factory.
Locking and other electronics modules
For DLC pro, the versatile DLC pro LOCK option is available as well as FALC pro and PDH/DLC pro modules. With DLC ext a number of analog locking modules is available.
19" Rack Integration
Modular integration into 19" industry rack to save space and ensure mobility.
Specifications
The company, now named TOPTICA, has grown and thrived over 30 years to become the undisputed world market leader in scientific diode lasers.

TOPTICA’s way of working ideally combines the qualities of research physicists, which include the drive to develop innovative concepts, with qualities necessary for success in the market. The latter include efficiency and cost-consciousness in the planning and implementation of measures. These qualities are widespread among the many talented people working at TOPTICA.
