Abstract

An extended-solid phase, carbon dioxide phase V (CO 2 -V), was synthesized in a diamond anvil cell by laser heating the molecular orthorhombic phase, carbon dioxide phase III, above 40 gigapascals and 1800 kelvin. This new material can be quenched to ambient temperature above 1 gigapascal. The vibration spectrum of CO 2 -V is similar to that of the quartz polymorph of silicon dioxide, indicating that it is an extended covalent solid with carbon-oxygen single bonds. This material is also optically nonlinear, generating the second harmonic of a neodymium–yttrium-lithium-fluoride laser at a wavelength of 527 nanometers with a conversion efficiency that is near 0.1 percent.

  14. ]; and (iv) a “distorted” phase of CO 2 -IV which has been proposed as occurring between the stability fields of CO 2 -I and CO 2 -III (11). The phase boundary between CO 2 -I and CO 2 -III is not well understood. For example Raman studies were presented that showed the stability of CO 2 -III to be above 18 to 20 GPa [

  17. We observed a large pressure gradient of CO 2 that exceeds 10 to 20% of its maximum pressure between 10 and 70 GPa at ambient temperature which ranges from 10 to 20 GPa over a typical sample size of 100 μm in diameter. Such an unusually large pressure gradient has also been observed by others [

  19. ; (11)]. In fact our Raman studies show that CO 2 -I and CO 2 -III coexist over a large pressure region causing some complication in understanding the exact nature of the phase stability and boundary of CO 2 -I CO 2 -III and CO 2 -IV mentioned above in (7). Our x-ray data also show the broad nature of the diffraction pattern of CO 2 -III above 30 GPa which is probably due to the large pressure gradient and the increase in materials strength at these pressures.

  21. In this study we measured the radiance of the SH emission; for example the radiance measured at 527 nm is ∼10 mW sr –1 mm –2 nm –1 at the expense of the total input laser power of 10 to 20 W at 1054 nm. This translates to ∼20 mW of radiation at the sample or 0.1% conversion. Considering the fact that much of the primary input laser light is also consumed for heating the sample we consider this conversion efficiency as a lower bound.

  23. The correspondence between the mode frequencies for the two structures was estimated by considering the ratio of the reduced vibrational masses for the symmetric stretching modes in singly bonded C–O–C and Si–O–Si structures. The angle between the two X–O single bonds was chosen to match the α-quartz bond angle (104.6°). The low-frequency limit (398 cm –1 ) results from the consideration of isolated structures (X 2 O molecules) whereas the high-frequency limit (491 cm –1 ) results from the consideration of the second-order shell of O atoms moving rigidly with C (Si).

  29. In general the SH of light is generated in noncentrosymmetric crystals whereas only odd harmonics are observed in centrosymmetric crystals. This stems from the second-order polarization dependence of electromagnetic transitions. In crystals having a center of symmetry the inversion of all coordinates must leave all relations between physical quantities unchanged. Because the electric field E is odd under inversion operations the polarization field P must also be odd and the coefficients of all even powers in the expansion of the polarization P = ε o χ 1 E sin(ω t ) + ε o χ 2 E 2 sin 2 (ω t ) + ε o χ 3 E 3 sin 3 (ω t ) + … must be 0; ε o dielectric constant at ambient conditions; χ polarizability tensor for medium; ω frequency of incident light; and t time. In such crystals only odd multiples of the incident frequency can be generated.
