2 Non-critical phase matching (Type II) is disallowed in uniaxial materials with 4mm symmetry, and critical phase matching (Type I) is possible only at wavelengths greater than λ. - 2.0μ. Private communication with Keith Kendall, Pennsylvania State University.

4 Subsequent technical obstacles may include photorefractive effects (“optical damage”) and difficulties in microlithographic fabrication of the structures.
5 At λ. = 1.06μ for bulk single crystals, nBT = 2.322 and nSW = 2.315. A related problem is the magnitude of both the SrTi03 and BaTiO3 refractive indices compared to air at the outer interface. A high index film deposited on top of the BaTi03 can reduce its required thickness, but adds undesirable complexity.

10 In addition, we have used this technique to deposit BaTiO3, TlBaCaCuO, LaSrCo03, Cr205, MgAI204, Y203-ZrO2(YSZ) and PbLaZrTi03. We have also demonstrated reagent delivery for CVD of Ta205 and Cu.
11 An optical reflectance thickness monitor may be used if it becomes necessary for more precise control.

16 The back surface of each sample was roughened on 600 grit sandpaper and painted black to reduce contribution of the back surface to the signal. 17 The detector was used in a photoconductive mode, and a beam chopper and lock-in amplifier were used to reduce noise.
