The proven laser solution for quantum applications
DL pro
Narrow linewidth, tunable diode laser
The DL pro is a reliable ECDL made for quantum applications. Based on our +25 years experience in laser technologies, its unique design allows to provide almost all wavelengths between 369 nm and 1770 nm. Thousands of units have been produced so far, with power up to 400 mW and free running linewidth down to 0.6 kHz.
Its digital controller allows a stable performance, the GUI making the remote access easy. This is especially convenient when the DL pro rack version is requested. This laser is fully compatible with the extensive TOPTICA portfolio of driving electronics, software and accessories.

Applications
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 addtion, lasers are used to link different quantum systems (e.g. to connect quantum computers or quantum computing sububits), 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 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 dots & microcavaties
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
Isolators are used to protect the laser diode from back reflections. This not only prevents damage to the diode but also ensures untroubled single-mode operation and tuning. Fiber coupling with angle polished fibers (both ends) requires at least a single stage isolator.
Dual stage optical isolation
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.
Fiber delivery
Fiber Delivery (FD) is optionally available with TOPTICA's patented fiber coupler FiberDock and a suitable polarization maintaining (PM) fiber. FiberDock provides highest single-mode fiber coupling efficiencies, easy alignment and at the same time highest stability.
For most lasers, we specify a PER behind fiber of >20 dB with our Fiber Delivery option. Please also inquire about Long Life and High Power fibers as well as fiber splitters. Optical isolation is mandatory for fiber coupled diode laser systems.
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 but not for DL pro F systems. See Downloads section below.
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. This option is not available for DL pro F systems.
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.
