Abstract. The accurate measurement of ultrashort pulses is necessary to optimize pulse compression for nonlinear optics and strong field physics. Additionally, fieldsensitive time-domain techniques enable measuring femtosecond and sub-femtosecond dynamics. In this paper, we introduce a single-shot measurement to characterize fewcycle fields. This polarization-sensitive time-domain measurement can retrieve the waveform of pulses shorter than two-cycles in duration with a temporal window of hundreds of femtoseconds. We measure how the field changes after propagation through dispersive optics, and we measure the sub-femtosecond phase shift imposed by the nonlinear intensity dependent response of a dielectric. Real-time field measurements will benefit low repetition rate systems used in strong-field physics and attosecond science, while the large temporal window compliments Fourier transform spectroscopy.

“…Currently, to measure single shot CEP, a laser pulse ionizes a gas jet and the CEP is extracted by measuring the subsequent current difference between left and right electron detectors [149,150]. Another highly sensitive and simple technique to measure the absolute CEP of pulses spanning the telecommunications to terahertz spectral regions is electro-optic sampling, whereby a high-frequency probe pulse is used to measure the temporal structure of a low-frequency waveform [151]. As each of these methods require quite large, complicated, experimental setups, developing an ultrafast, nanoplasmonic method of detecting single shot CEP is important.…”

Abstract:As modern complementary-metal-oxide-semiconductor (CMOS) circuitry rapidly approaches fundamental speed and bandwidth limitations, optical platforms have become promising candidates to circumvent these limits and facilitate massive increases in computational power. To compete with high density CMOS circuitry, optical technology within the plasmonic regime is desirable, because of the sub-diffraction limited confinement of electromagnetic energy, large optical bandwidth, and ultrafast processing capabilities. As such, nanoplasmonic waveguides act as nanoscale conduits for optical signals, thereby forming the backbone of such a platform. In recent years, significant research interest has developed to uncover the fundamental physics governing phenomena occurring within nanoplasmonic waveguides, and to implement unique optical devices. In doing so, a wide variety of material properties have been exploited. CMOS-compatible materials facilitate passive plasmonic routing devices for directing the confined radiation. Magnetic materials facilitate time-reversal symmetry breaking, aiding in the development of nonreciprocal isolators or modulators. Additionally, strong confinement and enhancement of electric fields within such waveguides require the use of materials with high nonlinear coefficients to achieve increased nonlinear optical phenomenon in a nanoscale footprint. Furthermore, this enhancement and confinement of the fields facilitate the study of strong-field effects within the solid-state environment of the waveguide. Here, we review current stateof-the-art physics and applications of nanoplasmonic waveguides pertaining to passive, magnetoplasmonic, nonlinear, and strong-field devices. Such components are essential elements in integrated optical circuitry, and each fulfill specific roles in truly developing a chip-scale plasmonic computing architecture.

“…Recently, similar broadband high-brightness mid-infrared radiation have also been generated using high-power femtosecond lasers [9][10][11] at outstanding wavelength and power stability [12]. More intriguingly, the femtosecond nature of such output, especially when in the form of a stabilized frequency comb, opens the way to a multitude of time-and frequency-domain techniques [13][14][15] that can reveal ultrafast dynamics and drastically improve the speed, dynamic range, and many other aspects of spectroscopic measurements [16][17][18][19][20]. Solid-state lasers based on Cr 2+ -doped II-VI material, often called the Ti:Sapphire of the mid-infrared, are reliable sources for directly generating ultrashort femtosecond pulses in the 2-3 μm spectral range [21][22][23][24][25].…”

Received XX Month XXXX; revised XX Month, XXXX; accepted XX Month XXXX; posted XX Month XXXX (Doc. ID XXXXX); published XX Month XXXX Lasers based on Cr 2+ -doped II-VI material, often known as the Ti:Sapphire of the mid-infrared, can directly provide few-cycle pulses with super-octave-spanning spectra, and serve as efficient drivers for generating broadband midinfrared radiation. It is expected that the wider adoption of this technology benefits from more compact and costeffective embodiments. Here, we report the first directly diode-pumped, Kerr-lens mode-locked Cr 2+ -doped II-VI oscillator pumped by a single InP diode, providing average powers of over 500 mW and pulse durations of 45 fsshorter than six optical cycles at 2.4 µm. These correspond to a sixty-fold increase in peak power compared to the previous diode-pumped record, and are at similar levels with respect to more mature fiber-pumped oscillators. The diode-pumped femtosecond oscillator presented here constitutes a key step towards a more accessible alternative to synchrotron-like infrared radiation, and is expected to accelerate research in laser spectroscopy and ultrafast infrared optics.
