TOPTICA contributes to the field of pump–probe measurements with newest fiber technology which is outstanding in performance and versatility. A single laser system can be equipped with various outputs that are intrinsically optically synchronized down to the attosecond level. All of these can be configured individually to satisfy the experimental needs: Pulse durations as short as 15 fs or broad tuning ranges of 490 nm to 700 nm, 850 nm to 1000 nm or 980 nm to 2200 nm are available. Within the third generation of TOPTICA’s ultrafast fiber lasers a novel, versatile toolbox is available to realize even more advanced pump–probe spectroscopy schemes. The FemtoFiber dichro bioMP outputs two different wavelength simultaneously (1050/780 nm at 150 fs), while the system can control the relative time delay of both colors and the GDD as well.

The APE ScanDelay is a variable optical delay line, allowing the introduction of a well-defined time delay into an optical path – for example, for pump–probe measurements. The delay is periodically controlled by a fast scanning shaker at a frequency of up to 20 Hz.

The heart of APE’s optical delay line series is a special linear translation stage that is supplied together with appropriate control and drive electronics. The linear drive has been designed especially for optical applications. It combines low moving mass with compactness, reaching a high speed, as well as high precision and resolution. The delay drive moves frictionless, has a large and precise travel range, and allows for very small displacements without any stick-slip-effects.

The control electronic contains the motion driver and a quartz stabilized signal synthesizer. It can be synchronized with an external clock for a precise, phase-locked scanner movement.

The K2-ASOPS is a 60 MHz femtosecond laser optimized for pump–probe spectroscopy, enabling precise ultrafast measurements without the need for mechanical delay lines. Utilizing a patented single-cavity dual-comb architecture, it generates two highly stable pulse trains with a freely tunable repetition rate difference, allowing for asynchronous optical sampling (ASOPS) with exceptional timing precision.

Key advantages of pump–probe spectroscopy:

• Freely tunable repetition rate difference for optimal ultrafast signal sampling.
• Eliminates mechanical delay stages – improves stability, speed, and precision.
• Ultra-low relative timing noise – even when free-running due to shared cavity architecture.
• Compact, quasi-monolithic design – robust and reliable for both research and industrial applications.

Ideal for semiconductor wafer inspection, ultrafast material science, and molecular dynamics, the K2-ASOPS delivers the next-generation solution for high-resolution pump-probe spectroscopy.

Ready-to-use optical delay lines manufactured by Thorlabs include the drive system necessary for computer-controlled variation of optical path lengths. With delays up to 4,000 ps and time resolution down to 0.67 fs, these systems compliment our family of ultrafast optics and laser systems, including low-GDD beamsplitters, to serve various pump-probe applications.
