Evaluation of Three Techniques for Producing Laser Pulses of Nanosecond Duration


Book Description

Three devices, a short-pulse laser, a coaxial Pockel cell shutter, and a single-crystal transmission-line Pockel cell, have been evaluated as techniques for producing laser pulses approximately 1 nsec in duration. The short-pulse laser has produced pulses that range from 0.5 nsec to 2.0 nsec in duration with peak powers from 25 to 300 kW. Pulses 1.8 nsec in duration FWHM (full width at half maximum) with risetime of less than 0.4 nsec have been gated from Q-switched ruby laser pulses by the coaxial shutter, while pulses 1.3 nsec FWHM have been obtained in the same fashion with a transmission-line shutter.

Metallized Plastics 3


Book Description

This volume chronicles the proceedings of the Third Symposium on Metallized Plastics: Fundamental and Applied Aspects held under the auspices of the Dielectric Science and Technology Division of the Electrochemical Society in Phoenix, Arizona, October 13-18, 1991. This series of symposia to address the subject of metallized plastics was initiated in 1988 and the premier symposium was held in Chicago, October 10-12, 1988, followed by the second event in Montreal, Canada, May 7-10, 1990. The rroceedings of these two symposia have been properly documented ,2. The third symposium was a huge success like the previous two events, and all this is testimonial to the brisk interest and high tempo of R&D activity in the fie14 of metallized plastics. This further bolsters our earlier thinking that there was a conspicuous need to hold symposia on this topic on a regular basis and the fourth is planned for May 16-21, 1993 in Honolulu, Hawaii. The study of metallized plastics constitutes an important human endeavor l and as pointed out earlier there are myriad applications of metallized plastics ranging from very commonplace to exotic. Also a survey of the recent literature will reveal that both the fundamental and applied aspects of metallized plastics are being pursued with great vigor.
