SUBJECT: Trip Report
DATE: 6 October 1964
PLACE:
ATTENDEES:
1. The purpose of this trip was to monitor PAR's 212, 216, and
217 under Contract
0
2. PAR 216 "Exposure of Photo raphic Materials with Lasers" was
the major area of concern. is now at a point where they can state
with authority that there should be no problems when present and pre-
dictable future photographic films are exposed with coherent laser
radiation.
3. On September 2nd, was instructed to prepare a final
report on the portion of PAR 21 dealing with the film as a recording
media.
4. Investigation o xperiments on using a photograph. in
the laser's beam indicated that they were only duplicating work already
accomplished by under our laser enlarger contract. A sub-
sequent trip to to review their progress, confirmed that the work
was, in fact, duplicative. After a detailed comparison of both the C
and as directed to finish a set of experiments just
starting and then to terminate PAR 216 upon completion of their final
report.

5. PAR 217 "Optimization of the Laser" is running smoothly.
The present glass laser used in conjunction with potassium dihydrogen
phosphate (KDP) crystal produces the desired green radiation through
frequency doubling effects. The present experiments are designed to
increase the energy output of the system. [::]is currently experimenting
with Q switching techniques, and extremely high energy levels with
correspondingly low exposure times should result. Nevertheless, there
is a possible problem area on PAR 217. There have been recent announce-
ments of an Argon CW laser which lases in the blue green region; however,
the energy output of the Argon laser should be much less than the Q
switched neodymium doped glass and EDP crystal hookup even after bire-
fringent losses. I as directed to perform a literature search
and to obtain as much information as possible on the Argon lasers. A
re-evaluation of the project will be made when enough information is
available to weigh one approach against the other.
6. PAR 212 was examined very briefly because of lack of time.
had some fine examples of high-altitude color photography
available. The photography was the most encouraging that I have
seen to date. An intelligent and objective study is needed to determine
the true advantages of color. There is much to be said for and
against color; the hard part will be to get an objective evaluation.
