“…Further experiments will be devoted to optical parametric oscillation (OPO), using the proper cavity design and coating of the LGN crystal faces. Very recently, LGN exhibits a favorable set of optical properties for the application in mid-IR optical parametric amplification (OPA) [43] or optical parametric chirped pulse amplification (OPCPA) [44]. Ma's group theoretically evaluated the performance of LGN as the nonlinear crystal of a midinfrared OPA and calculated the key parameters of wide bandwidth OPCPA [21].…”

Midinfrared (IR) nonlinear optical (NLO) materials with high performance are vital in important technological applications in many civil and military fields. Very recently, langasite family compounds have attracted much attention due to their wide transparency to mid-IR region and ultrahigh laser damage threshold (LDT). In this brief review, three important compounds-LGS, LGN, and LGT-are investigated and analyzed based on available experimental data. The electrooptical (EO) Q-switch and mid-IR OPO applications are summarized in detail. Finally, promising search directions for new metal oxides that have good mid-IR NLO performances are discussed.

High harmonics from laser-ablated plumes are mostly generated from ionic species. We demonstrate that with ultrashort infrared (∼1.82 μm) driving lasers, high harmonics from laser-ablated manganese are predominantly generated from neutral atoms, a transition metal atom with an ionization potential of 7.4 eV. Our results open the possibility to advance laser-ablation technique to study the dynamics of neutral atoms of low ionization potential. Moreover, as manganese contains giant autoionizing resonance, intense and broadband high harmonics have been demonstrated from this resonance at energies from 49 to 53 eV. This opens the possibility to generate intense attosecond pulses directly from the giant resonances, as well as to study these resonances using high-harmonic spectroscopy.

“…Complete details of this laser source are given elsewhere. 36 We use these Signal or Idler beams as the main pulse (MP), which is then focused in the nonlinear medium (i.e., the carbon ablation plume produced by the PP), after a delay of few tens of nanoseconds (ns). This delay between the PP and the MP is needed to produce neutrals in the plasma plume for maximum harmonic output, as well as to relax the electron density gradient, which would have negative effects in the HHG process.…”

We demonstrate broad bandwidth and intense sub-100 eV high-order harmonics from diatomic carbon molecules driven by long-wavelength laser pulses. Up to now, one limitation of the intense carbon harmonic source driven by a 0.8 μm wavelength Ti:sapphire laser has been the low cutoff around ∼32 eV. In this paper, we show that this harmonic cutoff is extended to ∼70 eV by increasing the driving laser wavelength to 1.71 μm. Surprisingly, the carbon harmonic intensity is found to be high despite the long wavelength driving laser. Experiments show only ∼30% decrease in the harmonic intensity when changing the driving laser wavelength from 0.8 μm to 1.71 μm. Such intense sub-100 eV coherent X-rays would have important applications in various domains of science and technology.
