“…Examples are mercury-thiogallate (HgGa 2 S 4 ), d eff = 30.6 pm/V, or silver-thiogallate (AgGaS 2 ), d eff = 12.3 pm/V that both provide a high nonlinear coefficient and have recently become commercially available [43]. But compared to the materials mentioned above, they are either not completely transparent in the respective wavelength range, or, more important, they cannot provide broadband phase-matching.…”

We discuss a dual-stage optical parametric chirped-pulse amplifier generating sub-100-fs pulses in the mid-infrared at a repetition rate of 100 kHz. The system is based on a 1064 nm pump laser and a 3-4 µm difference frequency generation seed source derived from the output of a femtosecond fiber laser amplifier. Both lasers are commercially available, are diode-pumped, compact, and allow for turn-key operation. Here, we focus our discussion on the design and dimensioning of the optical parametric chirpedpulse amplifier. In particular, we review the available gain materials for mid-infrared generation and analyze the impact of different stretching scenarios. Timing jitter plays an important role in short-pulse parametric amplifier systems and is therefore studied in detail. The geometry of the amplifier stages is optimized through a full 3-dimensional simulation with the aim of maximizing gain bandwidth and output power. The optimized system yields output pulse energies exceeding 1 µJ and an overall gain larger than 50 dB. The high repetition rate of the pump laser results in an unprecedented average power from a femtosecond parametric system at mid-infrared wavelengths. First experimental results confirm the design and the predictions of our theoretical model.

Abstract:We present a technique to characterize ultrashort pulses at the focal plane of a high numerical aperture objective with unprecedented spatial resolution, by performing a FROG measurement with a single nanocrystal as nonlinear medium. This approach can be extended to develop novel phase-sensitive techniques in laser scanning microscopy, probing the microscopic environment by monitoring phase and amplitude distortions of femtosecond laser pulses.

“…The direction of the Poynting vector, which is the direction of energy flux, is given by the normal to the tangent that touches the n(θ)-curve at its intersection with the k-vector. The angular difference between these two directions is denoted as the walk-off angle and is given for a negative uniaxial crystal [35] tan ρ = n o n e 2 tan θ − θ (1.14)…”
