Short-pulse oscillator for SHIVA
(1978)
An actively mode-locked and Q-switched Nd:YAG laser has been developed with pulse widths adjustable from ~100 ps to 1 ns, stability better than ±5%, and a single pulse energy of more than 200 μJ over this range
Optical rise-time measurements on KD*P transmission-line Pockels cells
(1978)
A technique has been developed for determining the optical-transmission rise times of subnanosecond switching KD*P electro-optic modulators. Optical streak-camera data with 15-psec overall resolution and 30-psec resolution ...
Shaping pulses for fusion
(1977-06-01)
Two approaches to the creating of pulse-shaping techniques that meet the requirements associated with operation of a large fusion laser are examined. These techniques are passive pulse-shaping with double-etalone devices ...
Improved isolation and culture methods for cucumber mesophyll protoplasts
(1977-05-01)
Improved methods for the isolation of large numbers of viable protoplasts from cotyledons and first leaves of two cultivars of cucumber, Cucumis sativus L. cv. Ashley and China are described. Short-term isolation methods ...
Pulse stretching and spectroscopy of subnanosecond optical pulses using a Fabry-Perot interferometer
(1977-04)
A Fabry-Perot interferometer has been used to produce optical pulses of variable width from a short gaussian input pulse. Pulse stretching of two to five or more times the original pulse width is possible provided a longer ...
Ribonucleic acid synthesis by chromatin isolated from Phaseolus aureus Roxb. : The effect of endogenous ribonuclease
(1977-01-01)
Chromatin was isolated from the hypocotyls of Phaseolus aureus Roxb. and assayed for endogenous RNA polymerase (EC 2.7.7.6) activity in vitro. The molecular size of the RNA product, measured by polyacrylamide gel ...
