“…Nonlinear optical phenomena, which are nonlinear with the optical intensity and are observed with pulsed lasers with high intensity, are one of the promising techniques that have been continuously developed since the first demonstration in 1961 [ 26 , 27 , 28 , 29 ]. This optical phenomenon has been used for various applications, such as the characterization of short and ultrashort pulsed lasers [ 30 , 31 , 32 ] and surface characterization [ 33 , 34 ], and is also used in image sensing techniques such as bioimaging [ 35 , 36 , 37 , 38 ].…”

This paper proposes a new optical angle measurement method in the optical frequency domain based on second harmonic generation with a mode-locked femtosecond laser source by making use of the unique characteristic of the high peak power and wide spectral range of the femtosecond laser pulses. To get a wide measurable range of angle measurement, a theoretical calculation for several nonlinear optical crystals is performed. As a result, LiNbO3 crystal is employed in the proposed method. In the experiment, the validity of the use of a parabolic mirror is also demonstrated, where the chromatic aberration of the focusing beam caused the localization of second harmonic generation in our previous research. Moreover, an experimental demonstration is also carried out for the proposed angle measurement method. The measurable range of 10,000 arc-seconds is achieved.

Infrared femtosecond optical vortices open up many new research fields, such as optical micro-nano manipulation, time-resolved nonlocal spectroscopy in solids, vortex secondary radiation and particle generations. In this letter, we demonstrate a femtosecond optical vortex laser system based on a two-stage optical parametric amplifier. In our experiment, 1.45 μm vortex signal pulses with energy of 190 μJ and 1.8 μm vortex idler pulses with energy of 158 μJ have been obtained, and the pulse durations are 51 fs and 48 fs respectively. Both the energy fluctuations of the signal and idler pulses are less than 0.5% (RMS), and the spectral fluctuations are less than 1.5% within one hour. This type of highly stable femtosecond optical vortex laser has a wide range of applications for vortex strong-field physics.

“…The temporal and spectral characterizations of the compressed pulse are shown in Fig. 3, which are measured by a home-built second-harmonicgeneration frequency-resolved optical gating (SHG-FROG) device [39]. By scanning the time domain of two beams that are non-colinear at the frequency doubling crystal combined, we can obtain the reconstructed FROG traces and retrieve the time domain characteristics of the pulse from the inversion.…”

In attosecond and strong-field physics, the acquisition of few-cycle laser sources open up a new area. We report a nonlinear pulse compression technology combining multi-thin-plate spectral broadening and nonlinear self-compression that generates a 0.52 mJ, good spatial quality characteristics and a spectral bandwidth supporting a 14 fs Fourier transform limited duration at 1 kHz repetition rate and at a center wavelength of 1.9 μm. The total energy transfer efficiency is up to 83%. Pulse to pulse stability of the energy output is 0.7% (RMS). The pulse duration is near 3 optical cycles. This pulse compression approach can be a key-enabling technology for the next generation of extreme photonics, attosecond research and coherent x ray-science, and it also can be further extended to midinfrared lasers with longer wavelengths and higher peak power.
