“…[15,16] Wang et al studied the influence of pressure on the SHG tensor of KBOC in 2013. [17] Han et al [18] and Gong et al [19] investigated the electronic, elastic, piezoelectric, acoustic, and the Raman spectroscopic properties based on first-principles in 2013 and 2014, respectively. The calculated thermal conductivities of KBOC at 60 • C are 2.21 W•m −1 •K −1 and 1.98 W•m −1 •K −1 along a and c axes, respectively, which is larger than that of BBO along the c axis (1.2 W•m −1 •K −1 ).…”

K 3 B 6 O 10 Cl (KBOC), a new nonlinear optical crystal, shows potential advantages for the generation of deep ultraviolet (UV) light compared with other borate crystals. In this paper we study for the first time the second harmonic generation (SHG) of a femtosecond Ti:sapphire amplifier with this crystal. Laser power is obtained to be as high as 220 mW at the central wavelength of 396 nm with a 1-mm-long crystal, and the maximum SHG conversion efficiency reaches 39.3%. The typical pulse duration is 83 fs. The results show that second harmonic (SH) conversion efficiency has the room to be further improved and that the new nonlinear crystal is very suited to generate the high efficiency deep ultraviolet laser radiation below 266 nm.

Up to now, at least 806 carbon allotropes have been proposed theoretically. Three interesting carbon allotropes (named Pbam-32, P6/mmm, and I 4 ¯ 3 d ) were recently uncovered based on a random sampling strategy combined with space group and graph theory. The calculation results show that they are superhard and remarkably stable compared with previously proposed metastable phases. This indicates that they are likely to be synthesized in experiment. We use the factor group analysis method to analyze their Γ -point vibrational modes. Owing to their large number of atoms in primitive unit cells (32 atoms in Pbam-32, 36 atoms in P6/mmm, and 94 atoms in I 4 ¯ 3 d ), they have many Raman- and infrared-active modes. There are 48 Raman-active modes and 37 infrared-active modes in Pbam-32, 24 Raman-active modes and 14 infrared-active modes in P6/mmm, and 34 Raman-active modes and 35 Raman- and infrared-active modes in I 4 ¯ 3 d . Their calculated Raman spectra can be divided into middle frequency range from 600 cm−1 to 1150 cm−1 and high frequency range above 1150 cm−1. Their largest infrared intensities are 0.82, 0.77, and 0.70 (D/Å)2/amu for Pbam, P6/mmm, and I 4 ¯ 3 d , respectively. Our calculated results provide an insight into the lattice vibrational spectra of these sp3 carbon allotropes and suggest that the middle frequency Raman shift and infrared spectrum may play a key role in identifying newly proposed carbon allotropes.

“…[14] The research on new NLO crystals with excellent NLO response has been enthusiastically carried out for DUV pulses generation by employing the SFG technique. Recently, using Ba 1−x B 2−y−z O 4 Si x Al y Ga z (x = 0 ∼ 0.15, y = 0 ∼ 0.01, z = 0 ∼ 0.04, x 2 + y 2 + z 2 = 0, BBSAG) crystal, DUV pulses with high repetition in a tunable range of 192.5 nm-210 nm was demonstrated by Meng et al [15] In 2015, a novel high quality NLO crystal called K 3 B 6 O 10 Cl (KBOC) with size up to 35 mm×35 mm ×11 mm was presented by Wu et al [16] Prior to this report, a series of studies on the properties of KBOC has been performed, such as the structure and NLO properties, [17] the influence of pressure on the SHG tensor [18] and the electronic, elastic, piezoelectric, acoustic, and Raman spectroscopic properties. [19,20] However, the SFG from KBOC has not been reported.…”

The third harmonic generation (THG) of a linear cavity Ti:sapphire regenerative amplifier by use of a K 3 B 6 O 10 Cl (KBOC) crystal is studied for the first time. Output power up to 5.9 mW is obtained at a central wavelength of 263 nm, corresponding to a conversion efficiency of 4.5% to the second harmonic power. Our results show a tremendous potential for nonlinear frequency conversion into the deep ultraviolet range with the new crystal and the output laser power can be further improved.
