High-power regenerative Nd:phosphate glass amplifier.
A compact high-power regenerative Nd:phosphate glass amplifier is described which incorporates spatial filtering and full image relay techniques. Output energies up to 1.2 J at a pulse duration of 140 ± 10 psec (FWHM) and 3 J at 900 ± 70 psec (FWHM) are achieved in a smooth nearly flattop beam intensity profile. Even with present-day technology, this system could be scaled into a terawatt regime.
Many-pass resonant laser amplifier
A very high gain amplifier has been developed by arranging for many amplifying passes to be made through one system. Input pulses of millijoule energy have been amplified to the damage limit of the materials (∼10 J/cm2) by this method. One such system can replace several when amplification of low-energy pulses is required.
RIP - General Purpose Interactive Display at HHIRF
RIP is a general purpose interactive code for display and analysis of data acquired with the Holifield Heavy Ion Research Facility (HHIRF) accelerators at Oak Ridge National Laboratory. The HHIRF data acquisition system includes a version of RIP for on-line display of one-and two-dimensional histograms on color graphic terminals and hard copy on color printer/plotters. General features of the program and interactive techniques will be described.
