We review the physical properties, linear and nonlinear optical characteristics, and phase-matching configurations of BiB3O6 (BIBO), the first low-symmetry (monoclinic) inorganic nonlinear crystal that has found broad applications for frequency conversion of laser sources from the UV, across the visible, to the near-IR based on three-wave interactions. We describe in detail the most relevant optical properties that make this material an attractive candidate for nonlinear frequency conversion of laser light in general, and ultrafast femtosecond laser sources in particular. With special focus on ultrafast frequency conversion, characteristics such as group-velocity mismatch and spectral acceptance, parametric gain bandwidth, group-velocity dispersion, as well as angular acceptance and spatial walk-off are evaluated and optimum configurations for the attainment of maximum conversion efficiency, minimum pulse duration, and highest spatial beam quality are identified and compared with the most widely established alternative borate crystal, β-BaB2O4. Experimental results are presented on both parametric up-and down-conversion of femtosecond pulses, from the high-energy, low-repetition-rate (1 kHz) to the low-energy, high-repetitionrate (56-76 MHz) regime, demonstrating the unique versatility of BIBO for efficient frequency conversion of femtosecond pulses with broad tunability from 250 nm in the UV, throughout the visible, up to ∼ 3000 nm in the IR.Photograph of a femtosecond synchronously pumped optical parametric oscillator (SPOPO) based on BiB3O6 emitting in the yellow region of the spectrum. Pumped near 400 nm in the blue by the second harmonic of a Kerr-lens mode-locked Ti:sapphire laser, the SPOPO can generate femtosecond pulses across the full visible range of 480-710 nm, from the blue-green, through to yellow, orange and red.

“…Hence the intensities and wavenumber shifts of the characteristic peaks assigned in Table 2 are obviously not same as those reported previously. 12 Comparison of our Raman results in LOBO with the Raman spectra of BBO 13 shows that more Raman peaks with higher intensities were observed at low wavenumbers in both of these compounds. This shows that the external vibrations of the anionic groups are very similar, although their six-membered B-O rings forming the crystal structural frameworks were associated with the different B-O polyhedra.…”

Li 2 O·3B 2 O 3 or Li 2 O.B 2 O 3 / 3 (LOBO) crystallizes in the orthorhombic space group Pna2 1 with cell parameters a = 0.73788(6), b = 0.84473(7) and c = 0.51395(5) nm and two formula units in the primitive cell. Raman results show that the characteristic spectra of LOBO are mainly contributed by particularly the B(3) -O tetrahedra and also the B(1) -O and B(2) -O triangles and partly ascribed to the breathing vibrations of the B -O rings. The structural rigidity of LOBO is associated with all B -O bond stretching and bending of especially the B(3) -O bonds. The excellent non-linear optical properties of LOBO are mainly attributed to the more anionic groups in the primitive cell and their deviations from the T d or D 3h symmetry. The short ultraviolet absorption edge is mainly attributable to the tilt of the B -O rings. The lattice thermal vibrations show that the anisotropically thermal conductivity is outstanding especially along the c direction.

“…Detailed studies of the lattice dynamics are required for a quantitative description of these bonds. Infrared (IR) and Raman studies of the phonons are so far only available at room temperature [3,[5][6][7][8]. In particular, there is no polarization-dependent infrared study, but a polarization analysis is essential for an accurate determination of the phonon frequencies in monoclinic crystals [9].…”

IntroductionBismuth triborate, BiB 3 O 6 , a polar, non-ferroelectric crystal has attracted interest in the last years due to its outstanding nonlinear optical properties [1][2][3]. The large optical nonlinearities open up a rich field of applications for frequency conversion of laser light via χ (2) -and χ (3) -processes, e.g. phase-matched second harmonic-generation (SHG) or optical parametric oscillation (OPO) and stimulated Raman scattering (SRS).The exceptional optical non-linearities of BiB 3 O 6 have been attributed to the bonds of the [BO 3 ] units and to a lone-pair electron at the Bi ion [4]. Detailed studies of the lattice dynamics are required for a quantitative description of these bonds. Infrared (IR) and Raman studies of the phonons are so far only available at room temperature [3,[5][6][7][8]. In particular, there is no polarization-dependent infrared study, but a polarization analysis is essential for an accurate determination of the phonon frequencies in monoclinic crystals [9]. In this letter we present a detailed investigation of the linear optical response of BiB 3 O 6 in the phonon range for different polarizations at T = 20 K and 300 K. The data are analyzed in terms of a generalized Drude-Lorentz model, which allows us to obtain the frequency, the damping, the strength and the orientation of the dipole moment of each phonon mode.
