Capillary Discharge X-Ray Laser

View page
US Patent:
7251263, Jul 31, 2007
Filed:
May 23, 2005
Appl. No.:
11/136617
Inventors:
Jorge J. Rocca - Fort Collins CO, US
Assignee:
Colorado State University Research Foundation - Fort Collins CO
International Classification:
H01S 3/22
H01S 3/095
US Classification:
372 61, 372 55, 372 89
Abstract:
A compact, high repetition rate, extreme ultraviolet/soft x-ray laser and method for generating such radiation are described. Excitation of the gaseous or vaporous lasing medium is achieved by discharging energy stored in a solid-dielectric capacitive device through a capillary channel containing the medium. By reducing the inductance of the discharge apparatus, excitation of the laser medium can be achieved without the use of Marx generators. Neon-like Ar atom laser pulses at 46. 9 nm having energies of about 13 μJ are generated at repetition rates up to 12 Hz. Between 2 and 3×10laser shots can be generated using a single capillary. Such a source of intense, short-wavelength radiation can be used for applications which include surface characterization of materials, high resolution imaging and printing, photochemistry and photophysics, laser ablation, characterization of x-ray optics, and dense plasma diagnostics.

Increased Laser Output Energy And Average Power At Wavelengths Below 35 Nm

US Patent:
7308007, Dec 11, 2007
Filed:
Dec 23, 2004
Appl. No.:
11/021217
Inventors:
Jorge J. Rocca - Fort Collins CO, US
David Alessi - Fort Collins CO, US
Bradley M. Luther - Fort Collins CO, US
Mark Berrill - Colorado Springs CO, US
Miguel A. Larotonda - Fort Collins CO, US
Yong Wang - Fort Collins CO, US
Assignee:
Colorado State University Research Foundation - Fort Collins CO
International Classification:
H01S 3/30
H01S 3/14
H01S 3/091
US Classification:
372 5, 372 69, 372 76
Abstract:
Saturated tabletop lasers having increased output energy and operating at 5 Hz repetition rate, were demonstrated at wavelengths about 18. 9 nm for molybdenum targets, 16. 4 nm for ruthenium targets, 14. 7 nm for palladium targets, 13. 9 nm for silver targets, and 13. 2 nm for cadmium targets in transitions of nickel-like ions. The results were obtained using a sequence of two, plasma-generating pre-pulses, each having sub-Joule energy followed after a selected delay period by picosecond laser plasma excitation pulses having with an energy of about 1 J at angles of incidence optimized for maximum energy deposition.

Renewable Laser Target

View page
US Patent:
7609816, Oct 27, 2009
Filed:
May 21, 2007
Appl. No.:
11/751568
Inventors:
Jorge J. Rocca - Fort Collins CO, US
Assignee:
Colorado State University Research Foundation - Fort Collins CO
International Classification:
H01J 35/08
US Classification:
378143, 378125
Abstract:
Generation of 2 μW average output power at 13. 9 nm from a table-top laser-pumped Ni-like Ag laser operating at 5 Hz repetition rate using a silver-coated helical target which is rotated and advanced such that the target surface is renewed between pulses, is described. Greater than 2×10soft x-ray laser pulses were obtained using a single target. Similar results were obtained at 13. 2 nm for Ni-like Cd using a cadmium-coated target. Uninterrupted operation of laser-pumped soft x-ray lasers at a repetition rates of about 10 Hz for periods of several hours enables the generation of pulsed, high average power soft x-rays for applications. Other embodiments of the renewable laser target are described.

Nanometer-Scale Lithography Using Extreme Ultraviolet/Soft X-Ray Laser Interferometry

View page
US Patent:
7705332, Apr 27, 2010
Filed:
Aug 17, 2007
Appl. No.:
11/840890
Inventors:
Mario C. Marconi - Fort Collins CO, US
Carmen S. Menoni - Fort Collins CO, US
Jorge J. Rocca - Fort Collins CO, US
Assignee:
Colorado State University Research Foundation - Fort Collins CO
International Classification:
G03H 1/20
US Classification:
250504R, 2504921, 2504922, 2504931, 355 53, 359 4, 359 12
Abstract:
Direct patterning of nanometer scale features by interferometric lithography using a 46. 9 nm laser is described. Multiple exposures using a Lloyd's mirror interferometer permitted printing of arrays having 60 nm FWHM features.

High-Order Harmonic Generation In A Capillary Discharge

View page
US Patent:
7729403, Jun 1, 2010
Filed:
May 21, 2007
Appl. No.:
11/804888
Inventors:
Jorge J. Rocca - Fort Collins CO, US
Henry C. Kapteyn - Boulder CO, US
Margaret M. Mumane - Boulder CO, US
David Gaudiosi - Orlando FL, US
Michael E. Grisham - Fort Collins CO, US
Tenio V. Popmintchev - Boulder CO, US

Assignee:
Colorado State University Research Foundation - Fort Collins CO
Regents of the University of Colorado, a body corporate - Denver CO
International Classification:
H01S 3/03
US Classification:
372 61, 250504
Abstract:
A pre-ionized medium created by a capillary discharge results in more efficient use of laser energy in high-order harmonic generation (HHG) from ions. It extends the cutoff photon energy, and reduces the distortion of the laser pulse as it propagates down the waveguide. The observed enhancements result from a combination of reduced ionization energy loss and reduced ionization-induced defocusing of the driving laser as well as waveguiding of the driving laser pulse. The discharge plasma also provides a means to spectrally tune the harmonics by tailoring the initial level of ionization of the medium.

Nanometer-Scale Ablation Using Focused, Coherent Extreme Ultraviolet/Soft X-Ray Light

International Classification:
B29C 67/00
US Classification:
264400, 4251744
Abstract:
Ablation of holes having diameters as small as 82 nm and having clean walls was obtained in a poly(methyl methacrylate) on a silicon substrate by focusing pulses from a Ne-like Ar, 46. 9 nm wavelength, capillary-discharge laser using a freestanding Fresnel zone plate diffracting into third order is described. Spectroscopic analysis of light from the ablation has also been performed. These results demonstrate the use of focused coherent EUV/SXR light for the direct nanoscale patterning of materials.

High Repetition-Rate, All Laser Diode-Pumped Extreme Ultraviolet/Soft X-Ray Laser And Pump System

View page
US Patent:
20100040105, Feb 18, 2010
Filed:
Aug 17, 2009
Appl. No.:
12/542663
Inventors:
Jorge J. Rocca - Fort Collins CO, US
Bradley M. Luther - Fort Collins CO, US
Brendan A. Reagan - Fort Collins CO, US
Federico J.A. Furch - Fort Collins CO, US
Assignee:
XUV, Inc. - Fort Collins CO
International Classification:
H01S 3/0941
US Classification:
372 75
Abstract:
An extreme ultraviolet/soft x-ray laser driven by a compact solid-state chirped pulse amplification laser system entirely pumped by laser diodes is described. The solid-state pump laser generates compressed pulses of sub-10 ps duration with energy greater than 1 J at a chosen repetition rate in a cryogenically cooled Yb:YAG system. Lasing in the 18.9 nm line of Ni-like Mo was observed. The diode-pumped laser has the potential to greatly increase the repetition rate and average power of lasers having a variety of EUV/SXR wavelengths on a significantly smaller footprint.
