  • Publication number: 20140017416
    Abstract: A p-type semiconductor zinc oxide (ZnO) film and a process for preparing the film are disclosed. The film is co-doped with phosphorous (P) and lithium (Li). A pulsed laser deposition scheme is described for use in growing the film. Further described is a process of pulsed laser deposition using transparent substrates which includes a pulsed laser source, a substrate that is transparent at the wavelength of the pulsed laser, and a multi-target system. The optical path of the pulsed laser is arranged in such a way that the pulsed laser is incident from the back of the substrate, passes through the substrate, and then focuses on the target. By translating the substrate towards the target, this geometric arrangement enables deposition of small features utilizing the root of the ablation plume, which can exist in a one-dimensional transition stage along the target surface normal, before the angular width of the plume is broadened by three-dimensional adiabatic expansion.

  • Patent number: 8497490
    Abstract: A terahertz wave generation device is provided with an ultra-short pulse laser light source (3) for generating ultra-short pulse laser light at a single repeating frequency and optical fibers (F1 to F5) for respective transmitting and projecting of the ultra-short pulse laser light to an LN crystal (15). Projection units (13) of the optical fibers (F1 to F5) are made parallel to irradiate the ultra-short pulse laser light (L) projected from the projection units (13), respectively, on terahertz transmission line (A) in the LN crystal (15) with sequential delays. The optical lengths of the transmission paths of the optical fibers (F1 to F5) are set longer as the transmission paths go closer to one side of the parallel direction of the projection units (13).

  • Patent number: 7907334
    Abstract: A chirped pulse amplifier (CPA) system having a mode-locked laser and a high-speed pulse selector, wherein the pulse selector modulates output pulses based upon an applied modulation voltage. A pulse selector may be an integrated electro-optic modulator, for example a LiNbO3 modulator, or an electro-absorption modulator. Difficulties related to free-space alignment and operational stability of some prior designs are reduced or eliminated. Fiber coupling generally simplifies beam delivery and alignment. Some embodiments include an erbium fiber (or erbium-ytterbium) based CPA system operating at a wavelength of approximately 1550 nanometers. Similar performance can be obtained at other wavelengths, for example a 1.06 micrometer Yb-doped fiber system. Moreover, high amplification and peak intensity at the output may be achieved while avoiding non-linear effects in the pulse selector, thereby providing for high intensity picosecond or femtosecond operation.

  • Publication number: 20090246530
    Abstract: A method of pulsed laser deposition (PLD) capable of continuously tuning formed-film morphology from that of a nanoparticle aggregate to a smooth thin film free of particles and droplets. The materials that can be synthesized using various embodiments of the invention include, but are not limited to, metals, alloys, metal oxides, and semiconductors. In various embodiments a ‘burst’ mode of ultrashort pulsed laser ablation and deposition is provided. Tuning of the film morphology is achieved by controlling the burst-mode parameters such as the number of pulses and the time-spacing between the pulses within each burst, the burst repetition rate, and the laser fluence. The system includes an ultrashort pulsed laser, an optical system for delivering a focused onto the target surface with an appropriate energy density, and a vacuum chamber in which the target and the substrate are installed and background gases and their pressures are appropriately adjusted.
