Titre: Purchase a state-of-the-art ultrafast high- pulse-energy / variable-repetition-rate laser system from Amplitude
Description: The FELIX laboratory is an international user facility that hosts a suite of free-electron lasers (FELs) that deliver picosecond-long optical pulses that are highly tunable in wavelength in the infrared spectral range. For the project devoted to studying how circularly-polarized optical phonons interact with magnetization on ultrashort timescales, a state-of-the-art table-top probing laser system is required, that will need to meet diverse and complex requirements in terms of temporal resolution, pulse energy, variable repetition rates and triggering. To the best of our knowledge, Amplitude is the only supplier capable of delivering a laser system that complies with these challenging requirements. In the following, we specify the unique characteristics of the table-top laser system that can be offered by Amplitude, and discuss how these render the proposed laser-system suitable for our project.

Justification de l’attribution directe: Le marché ne peut être exécuté que par un opérateur économique particulier en raison d’une absence de concurrence pour des raisons techniques
Autre justification: The free-electron lasers at FELIX deliver infrared pulses at a repetition rate of 50 MHz (more precisely, 49.9715 MHz). To therefore achieve ultrashort temporal resolution in pump-probe experiments, the oscillator embedded within the laser system can be designed to match this frequency, with corresponding electronics modules (with a piezo transducer) facilitating cavity-locking and synchronization to an external RF reference. In particular, the timing jitter between the oscillator output and the reference clock (fixed at 2998.29 MHz) is specified to be below 250 fs. Moreover, the offered laser-system contains an electronically-controlled remote delay line, enabling an infinite amount of 150-fs-long steps to be made with a scanning speed tunable between 250 fs/s to 250 µs/s. As well as facilitating two-color pump-probe experiments involving synchronization with the free-electron laser pulses, the offered laser-system can also operate as a stand-alone unit, allowing for experiments to be conducted in the absence of the free-electron lasers. The system offered by Amplitude is a compact hybrid laser that combines the best of two technologies (fiber and crystal) to amplify the oscillator-derived pulses. The oscillator is equipped with fiber-outputs to provide reliable and precise optical coupling to the amplification module. The latter is capable of producing pulses at the wavelength of 1030 nm with a duration <400 fs, linewidth <3 nm at full-width-at-half-maximum, and a power of 50 W. At the repetition rate of 50 MHz, this corresponds to a single pulse having an energy of 1 µJ. The infrared pulses delivered by FELIX at the rate of 50 MHz are by default enclosed within 10-µs-long bursts (“macropulses”). It is therefore crucial that the pulses delivered by the proposed laser-system can be similarly ‘carved’, in order to match the temporal characteristics of the FELIX-delivered macropulses. With this purpose in mind, the offered laser system contains a built-in AOM, allowing the amplified pulse train coming at 50 MHz to be carved into macro-bursts of 50 MHz pulses spaced at 1/(10 Hz) intervals. This ability is essential for performing stroboscopic pump-probe measurements at a high repetition rate. Using the techniques of “pulse-slicing” or “cavity-dumping”, FELIX can also deliver single infrared pulses at a repetition rate of 10 Hz. At this repetition rate, we intend to use the pulses delivered by the offered laser-system for illumination within time-resolved pump-probe microscopy experiments. Thus, since the laser’s pulses will be defocused for this purpose, the pulse energy at lower repetition rates must be substantially higher. The AOM integrated within the laser-system also therefore needs to be capable of varying the repetition rate of the delivered pulses while simultaneously increasing the pulse energy at lower repetition rates. Amplitude is capable of providing this, with the energy of single pulses increasing to 500 µJ at the repetition rate of 100 kHz. Further, an additional pulse-picker within the laser system allows the repetition rate to be further downscaled to 10 Hz while preserving a pulse energy of 500 µJ. An additional complexity comes from the fact that the 10-Hz repetition rate of the macrobursts delivered by FELIX is derived not from the reference clock but rather the electrical grid. As such, it becomes compulsory to select exactly which pulses are amplified from the laser’s oscillator. Amplitude offers the ‘FemtoTrig’ solution which allows an external TTL signal to trigger the AOM and pulse-pickers integrated within the laser system. The laser system therefore delivers single pulses “on-demand” (at frequencies below 100 kHz, such as 10 Hz) with the same energy as pulses generated at 100 kHz. This is a particularly unique characteristic of the proposed laser system that is vital for its intended purpose. For the envisioned two-color pump-probe experiments, it will be mandatory to probe optical effects in the visible spectral range. The narrow spectral linewidth (<3 nm at FWHM) of the pulses delivered by the Amplitude’s laser-system render it ideal for second-harmonic generation (SHG), enabling pulses to be also delivered with a wavelength of 515 nm. The laser system is additionally equipped with an industrial-grade SHG module, suitable for delivering pulses of wavelength 515-nm at repetition rates between 10 Hz and 100 kHz, with a frequency-independent pulse-energy of ~250 µJ. This functionality is also achievable with pulses delivered “on-demand” via the FemtoTrig option. Moreover, the laser system allows for one to easily switch between the 1030-nm and 515-nm outputs, depending on the specific experiment being performed. The high pulse-energies offered by Amplitude’s laser-system even allow us to perform experiments where the 1030-nm pulses can serve as pump pulses within pump-probe spectroscopy. For this type of experiment, it will be important to be able to vary the duration of the pulses delivered by the laser system. This is provided by the laser’s compressor being placed on an automated controller stage, enabling the output pulses to be varied in duration from <400 fs to 10 ps. Amplitude also supply software that allows the laser’s output power, the repetition rate and the pulse energy to be tuned. Moreover, Amplitude offers a digital service allowing for the laser to be monitored and serviced remotely. All the laser components within the laser system are manufactured and/or supplied by Amplitude, allowing for Amplitude to directly service any component within the laser. Last but not least, the laser system has a small form-factor (730 × 320 × 260 mm), which is the smallest on the market for a laser of this class and energy. The above combination of characteristics of the laser offered by Amplitude render this system uniquely qualified for the project based at the FELIX facility. Thus, it is our intention to procure this laser source from Amplitude.
