Abstract

Diamond polycrystalline films synthesised by chemical vapour deposition (CVD) techniques present interesting features for laser spectroscopy due to several advantages arising from their optical, electronic, thermal and mechanical properties. Their wide transmission band from the far IR to the UV make them attractive as optical devices for high-power laser beam. Moreover, with a wide band gap (E_g = 5.5 eV or λ = 225 nm), a short carrier lifetime (typically ≤ 1 ns) and a high damage threshold, diamond is an ideal semiconductor material for the fabrication of fast and solar blind VUV detectors. We report here results of laser studies performed with two different objectives. With use of a pulsed VUV laser at 125 nm we have determined the photoconductive response of polycrystalline diamond detectors. With a CO₂ laser (10.6 μm) we have investigated the polarisation properties of auto-supported films having thicknesses smaller than the wavelength.
