Publication number: 20080037103Abstract: A deformable mirror formed out of two layers of a nanolaminate foil attached to a stiff substrate is introduced. Deformation is provided by an electrostatic force between two of the layers. The internal stiffness of the structure allows for high-spatial-frequency shapes. The nanolaminate foil of the present invention allows for a high-quality mirror surface. The device achieves high precision in the vertical direction by using foils with accurately controlled thicknesses, but does not require high precision in the lateral dimensions, allowing such mirrors to be fabricated using crude lithography techniques. Such techniques allow structures up to about the meter scale to be fabricated.Type: ApplicationFiled: August 8, 2006Publication date: February 14, 2008Inventors: Alexandros P. Papavasiliou, Scot S.

Publication number: 20080037108Abstract: To induce a targeted non-linear optical effect by a high-peak-power light by using a light pulse from a semiconductor laser without using a light pulse from a large, high-average-power solid laser such as titanium sapphire laser. A semiconductor laser pulse beam with a wavelength of 1550 nm (for example, repeatability of 1 MHz) from a semiconductor laser (laser diode: LD) is efficiently amplified in two stages, front-end and main EDFAs. An optical filter removes a spontaneous emission light component that is noise. An optical filter picks up, from the amplified pulse beam, second harmonic light pulse produced by the non-linearity of an optical device (frequency polarization inversion Mg-added LiNbO3:PPMgLN) to produce a super-continuum light in a 800 nm wavelength region from a photonic crystal fiber (PCF).Type: ApplicationFiled: June 30, 2005Publication date: February 14, 2008Inventor: Hiroyuki Yokoyama
