Ultrafast Laser
Ultrafast Laser: Octavius Laser Series

The Octavius series of ultrafast lasers provide, depending on the model, octave-spanning spectra with pulse durations less than 6 fs and up to 750 mW of output power at a repetition rate of 1 GHz or 85 MHz. The octave-spanning spectrum allows for carrier offset frequency stabilization. With an install base of more than 20 systems worldwide in applications reaching from calibration of Echelle spectrometers for exo-planet search (Ch. Li, et al.Nature,Vol 452, 2008) to seeding of OPCPA systems (Hemmer et al. Proc. SPIE, Vol. 7578, 757818 (2010)) or single molecule spectroscopy the Octavius has proven itself as a state-of the art and reliable research tool.

fs pulse characterization
2DSI - Two Dimensional Shearing Interferometry

Developed in close collaboration with MIT, Two-Dimensional Spectral Shearing Interferometry (2DSI) is a pulse measurement system that measures an ultrashort pulse envelope by interfering neighboring spectral components, similar to SPIDER. In contrast to SPIDER, however, 2DSI encodes the spectral group delay in the spectrum of a single nonlinearly transformed pulse, rather than two. This avoids the need to calibrate the delay between two pulses to high precision, a potential complication with SPIDER for few-cycle pulses and below.

Sputter-Coated Ultrafast Optics
Sputtered Ultrafast Optics: Dispersion compensation mirror set for non-linear microscopy

IdestaQE has unique expertise in designing complex thin-film mirrors. For example, the mirrors used in our Octavius product line feature more than 100 layers per mirror. As these mirrors are used in matched pairs, the overall mirror pair optimization problem has more than 200 variables. A newly-developed proprietary merit function for the mirror performance, as well as algorithms which can run in highly parallelized fashion on massive computer grids, allow idestaQE to bring thin film design to the next level.

To ensure the highest quality coatings, we work with the best optic shops and coating companies in the industry. All of our coatings are deposited by a high-energy-sputter-coating technique. Sputter coatings not only allow for the highest precision and purity during the coating process itself, but also produce extremely robust and shift-free coatings. An in-house white-light interferometer and reflectometer are employed for rigorous quality control on optics before they ship to customers.

Synchronization & Timing Distribution
Sub-10 fs large scale timing distribution and synchronization

Next generation light sources or free electron laser, such as FLASH at DESY, LCLS at Stanford or FERMI@ELETTRA in Trieste require essentially drift-free distribution of a timing reference signal, which is usually provided by a stable RF oscillator, throughout the facility. The conventional method of distribution, via RF-cabling, allows synchronization within approximately 100 fs (rms) long-term. In collaboration with Prof. F.X. Kaertner at MIT, we have developed and engineered two key-solutions for long-term stable, pulsed optical timing distribution and synchronization in the sub-10-fs (rms) regime: A long-term stable RF-to-optical as well as a highly sensitive optical-to-optical phase detector.
