The 13th international conference on laser interactions and related plasma phenomena.
We discuss the advantages of ultrashort pulses (ps-duration) for ground-based laser propulsion applications. Earlier, we introduced the ORION laser space debris removal system, and found that 10-ns, 15-kJ pulses in a 6-m-diameter beam were required t

We present a laser‐target scaling model which permits approximate prediction of the dependence of ablation pressure, mechanical coupling coefficient, and related parameters in vacuum upon single‐pulse laser intensity (I), wavelength (λ), and pul

Interband Faraday rotation in intrinsic germanium has been employed to construct a room‐temperature optical isolator for use in the intermediate infrared region. The device was tested at 9.55‐ and 10.59‐μm wavelengths, and exhibited an isolati

We have completed the conceptual design of a 170-MJ laser system consisting of two identical, opposing, 0·4 M-litre, 84-MJ HF subsystems, which together deliver 105 ‘useful’ MJ in 50 ns (FWHM duration) to a laser-fusion target during its hydrody

This paper presents the results obtained and the technique developed in a study of apple maggot ( Rhagoletis pomonella ) dispersal. A total of 1,035 flies were marked and liberated at one release point during the course of the experiment. Of this num

A stilt-bug, Jalysus Spinosus Say is recorded as a serious pest of the tomato in Missouri. It is distributed from Maine to the Rocky Mountains and commonly occurs on the undergrowth of oak woods. It causes the blossoms to wither up and drop off, prev

This paper records the recovery of 130 marked apple maggot (Rhagoletis pomonella Walsh) flies out of a total of 3,152 which were released in one site. These marked flies were recovered at distances varying from 65 to 233 yards from the point of relea

This paper deals with the life history of Rhagoletis pomonella Walsh in Maine. It presents data which indicate that time of fly emergence is governed by a number of factors. Some of these factors are: variety of fruit in which the larva develops; nat

Xanthonia Decem-Notata Say, previously unrecorded in economic literature, has been very destructive to the apple in one district in Maine. It has been recorded for a long time as an unimportant leaf feeder on the oak, beech, and elm. The beetle has a

A new class of saturable absorbers for 10‐μm applications using doped alkali halides is demonstrated. For the ReO−4 molecular ion in KCl, the vibrational transition saturates like an ideal two‐level system. This behavior is a result of the lar
