The new DL pro BFY is especially suitable for applications where a care-free operation of the lasers is required. It can even run as an outdoor system, equipped with temperature stabilization, to withstand massive winds and pressure fluctuations.

The DL pro is a reliable ECDL laser for almost all wavelengths between 369 nm and 1770 nm. With power up to 400 mW and free running linewidth down to 0.6 kHz, the DL pro is a proven solution for most QT applications. Its digital controller allows a stable performance, the GUI making remote access easy, which is very convenient when the DL pro rack version is requested. It is fully compatible with the extensive TOPTICA portfolio of tunable diode lasers, driving electronics, software and accessories.

"Our DFB pro 633 provides a mode-hop-free tuning range of 200 GHz. Driven by the DLC pro controller, it is ready to be integrated into OEM customers’ tools," explains Stéphane Junique, product manager for the DFB pro laser platform at TOPTICA.

The DFB pro 633 offers a mode-hop-free tuning range of 200 GHz. The DFB pro, a single-frequency laser based on a distributed-feedback (DFB) diode, covers wavelengths from 633 nm and 760 nm up to 3500 nm and offers a mode-hop-free tuning range of up to 1400 GHz. It is well-suited for a variety of applications, including semiconductor metrology and spectroscopy.

Distributed feedback (DFB) lasers unite wide tunability and high output power. The frequency-selective element – a Bragg grating – is integrated into the active section of the semiconductor and ensures continuous single-frequency operation. Due to the absence of alignment-sensitive components, DFB lasers exhibit an exceptional stability and reliability. The lasers work under the most adverse environmental conditions – even in the Arctic or in airborne experiments.

FemtoFiber ultra FD 780/920/1050 nm: A game-changer for simplifying multi-photon microscopy
Completely replacing the free-space paths between a watt-level femtosecond laser and a two-photon microscope is a game-changer for modern microscopy. By delivering femtosecond pulses directly from the laser source to the microscope via an optical fiber, users can enable entirely new microscope designs while significantly improving laser safety and usability.

With the FemtoFiber ultra FD there is no need for mirror alignment or power meters. Setup is fast and easy.

Featuring diode lasers with an ultra-narrow linewidth below 1 Hz, stabilized to high-finesse optical ULE cavities, the CLS achieves exceptional frequency stability far beyond 1-second integration time. This makes it an essential tool for driving the narrow atomic clock transitions of neutral atoms like Yb and Sr, as well as ions such as Yb+, Sr+, Ca+, and Ba+.

Engineered for real-world applications, the CLS combines robust passive shielding, active vibration compensation, and advanced temperature stabilization to ensure peak performance even outside laboratory environments. Whether for quantum computing, precision timekeeping, or quantum sensing, TOPTICA’s CLS sets a new benchmark in ultra-stable laser technology.

The system is controlled by a single interface, which is hosted by the DLC pro and can be accessed via the PC GUI TOPAS. The interface is responsible for controlling, monitoring and locking the laser, and supports full remote operation. This interface also allows for easy integration into the user experiment control via a convenient programming SDK.

The CLS can also be obtained as a rack solution (MCLS) that has been integrated into a TOPTICA T-RACK, without any compromise to the performance of the system. This solution is ideal for users who have limited space available, and it also enables the system to be transported with ease.

Utilizing readily available building blocks from TOPTICA’s product portfolio, the system delivers an impressive 80 W of optical output at 532 nm while simultaneously holding the relative intensity noise (RIN) to an exceptional level below 0.02% rms (10 Hz to 10 MHz).

The innovative combination of the narrow-linewidth external-cavity diode laser DL pro with a high-performance fiber amplifier ALS-1064-130 and the proven resonant frequency-doubling stage SHG pro significantly outperforms other, currently available DPSS or fiber-amplified based laser systems, which struggle to achieve the required combination of both high power and ultra-low noise.

The demonstrated performance enables technology advancements and higher throughput in areas such as titanium-sapphire laser pumping, leading-edge semiconductor inspection, and large-area holography.

The QUPICS team consists of AIM Photonics, Cornell University, Rochester Institute of Technology, Columbia University, Yale University, Air Force Research Laboratory, NIST, Quantinuum, Xanadu, and TOPTICA. Led by the American Institute for Manufacturing Integrated Photonics (AIM Photonics) and Cornell University, the team will develop a novel 300mm foundry fabrication platform for quantum technologies which will span the ultraviolet to the infrared. QUPICS will specially address the foundry gap for trapped ion, neutral atom, and photonic quantum technologies incorporating broadband photonics, electro-optic devices, multi-metal layer electrical functionality, and lasers into a single broadly available technology offering. QUPICS will develop and incorporate passive photonics, active components, and laser sources from the ultraviolet to the infrared geared to the use of quantum technologies. Integrated systems spanning this broad wavelength range are critical for a variety of photonics-heavy quantum systems for commercial and DoD priority applications in quantum sensing, networking, computation, and position navigation and timing (PNT). In later years QUPICS will open to multi-project wafer (MPW) runs and will be actively searching for partners from government laboratories, academia, and businesses.

“TOPTICA Photonics, Inc. is proud to partner with AIM Photonics, Cornell University and all the other great organizations that will contribute to this project,” said Mark Tolbert, CEO of TOPTICA Photonics Inc. “For more than two decades, TOPTICA has enabled quantum technologies and pushed innovation. We will do the same by developing chip-integrated lasers for the QUPICS project.”
