20090245294	Fibre Laser with Intra-cavity Frequency Doubling - The invention disclosed herein relates to fibre lasers with intra-cavity frequency doubling. In one embodiment, the invention is directed to a fibre laser with intra-cavity frequency doubling characterized in that a non-linear crystal of type II phase matching is used to thereby enable operation of the fibre laser without selection of polarisation of the generated fundamental radiation. The non-linear crystal is oriented so as to minimise the walk-off angle of the second harmonic radiation, and a second dichroic mirror together with one of a plurality of focusing elements forms a telescopic reflector that provides for focusing and compensation of the spatial walk-off effect of the non-linear crystal.	10-01-2009

20110133082	Scanning electron microscope - Example embodiments are directed to a scanning electron microscope. The scanning electron microscope includes an electron gun to configured irradiate an electron beam on a sample, and a disc of a transparent material and including a through-hole through which the electron beam passes. The disc includes a scintillator layer formed at a surface thereof so as to generate photons based on the secondary electrons received from the sample. A reflecting layer is formed at an inner peripheral surface of the through-hole so as to reflect the photons, thereby preventing leakage of the photons via the through-hole.	06-09-2011
