Ultra-stable laser systems are key to addressing narrow atomic transitions. Our expert Lukas Hartung explains how clock laser systems take this roll in today's and tomorrow' quantum applications. 

Over the years, optoelectronic terahertz instrumentation has improved in terms of both performance and robustness, and various industrial installations are already underway. This presentation reviews two of the most common concepts, i.e., time-domain and frequency-domain approaches, and presents the state-of-the-art as well as emerging applications for each technology.

Quantum technologies reliant on atoms or ions require lasers and downstream optical components, like optical isolators, wavelength references, and phase and intensity modulators. In this talk, the potential advantages of PIC-based lasers will be presented, including specification advantages in a stand-alone laser and the possibility to integrate lasers with many other on-chip components.

Watch the recorded joint discussion to learn how to protect your laser system from damage using optical isolators and coatings designed for high laser-induced damage threshold (LIDT). The drive towards higher-power lasers makes these considerations more important than ever before.

Absorption spectroscopy is a well-known tool for gas sensing, combustion diagnostics, and quantum technologies applications. Techniques like tunable laser absorption spectroscopy (TLAS) are straightforward for these applications, but not always suitable for low concentrations of molecules or transitions with low cross-section. TLAS is too noisy for absorption coefficients below approximately 10⁻⁴ cm⁻¹.

Heiniger details various techniques that can be used to improve sensitivity, all the way down to spectroscopy of single molecules.

Today’s emerging quantum technology applications are complex compared to those used in conventional laser end markets. Kock discusses some of the key requirements and building blocks that laser solutions targeting quantum applications must deliver, including reliable, high-performance tunable laser systems, highly robust frequency reference systems, and highly modular laser platform designs.

Multiphoton imaging in neuroscience has much evolved from the initial two-photon microscope that Winfried Denk built in Watt Webb’s lab at Cornell University in the late 1980s. Mastron discusses developments in multiphoton imaging in neuroscience, including contributions from disciplines such as biochemistry, signal processing, optics, and optoelectronics, and provides an overview of some technical advancements in the field for both a nonspecialist and specialist audience.

Optical frequency combs have gained a lot of attention due to their unique ability to act as a ruler in both time and frequency space, connecting the radio frequency spectrum to the visible and beyond. Matthew Cich presents the ways in which these properties are applied to spectroscopy and microscopy applications, discusses the benefits and challenges of integrating comb sources into instruments, and examines the near future of frequency combs as instrument light sources.

Konstantin Birngruber and Max Eisele introduce TOPTICA's next-generation laser technology by highlighting multicolor light engines for standard fluorescence microscopy, as well as TOPTICA's high-power fiber laser series for advanced two-photon fluorescence microscopy.

The FemtoFiber ultra 920 at an output wavelength of 920 nm is ideally suited for the two-photon excitation of common fluorophores like GFP, eGFP, Eosin, GCaMP, CFP, Calcein or Venus.

In two-photon microscopy, peak-power is brightness! If you care for the best image brightness, you need short pulses, high power, and most importantly a clean temporal pulse shape.

This webinar will talk through some of the ways in which we’re having to shift and adapt our customer and supplier interactions. We will discuss how to market to potential customers when we don’t have some of the standard options, like conferences and trade shows, available to us. As a corollary, we will also discuss how to most effectively seek new suppliers.
