The Big Bang Observer(BBO) is a proposed space-based gravitational wave detector which will look for the stochastic background of gravitational waves from the early universe. The positions of three free test masses, 50,000 km apart, will be monitored by laser interferometry. To reduce noise, 300 W of 355 nm light obtained from frequency-tripling the output of Nd:YAG lasers will be used. These lasers...
Ultrashort laser pulses improve micromachining but they suffer significant phase distortions when focused by microscope objectives. Breakthrough technology to correct high order phase distortions is used to improve the machining characteristics of metals and semiconductors.
Optics, photonics, and lasers are key components of Florida??s tech-based economy. This talk discusses the University of Central Florida??s focused education, research, commercialization, and industry partnership programs to support and grow this economic sector.
Surface radicals generated by 193 nm (nylon) or 172 nm (PET) UV light afford strongly antimicrobial amine functionality by grafting or by transformation. They are broadly effective in the lab and significantly viable in the field.
A real-time aerosol-particle monitoring system is developed to measure size, concentration, and UV-laser-induced-fluorescence spectra. Data for atmospheric particles at New Haven, CT are measured over 48-hours and heirarchically cluster into various categories.
Breakthrough technology in remote femtosecond pulse characterization and accurate delivery of ultrashort shaped pulses to distances greater than 30 meters is being used to develop remote detection of explosives as well as biological warfare agents.

Ripples (spacing <??/4) are obtained by scanning femtosecond laser radiation (??=100fs&400fs. ??=800nm&1045nm) over the surface of various materials. The ripple patterns extend coherently over many overlapping laser pulses and scanning tracks.
General description of the industrial laser processing market in China, prospect and developing trend of the china industrial laser processing market, introduction of Chutian Laser group and its products.
For long distances direct quantum communication via optical fiber is not viable, due to fiber losses. We will outline our program on the use of atomic ensembles for long distance quantum networks.
This paper presents overview on trends of domestic production of laser materials processing equipment and introduces some recently achieved technological advances in industrial laser applications in Japan with a slightly emphasis on micro-processing applications.
