EVALUATION OF FINAL REPORT ON PAR 21
Background
PAR 217 of Contract was concerned with the optimization of
the laser for photographic purposes. Its basic task was to explore
the production of 0.5 micron wavelength (blue-green) laser radiation
by harmonic doubling in certain bi-refringent crystals, those of
ammonium di-hydrogen phosphate I (ADP) and potassium di-hydrogen
phosphate (KDP). undertook the problem on 2 March 1961+
and completed the work on 12 October 1965 at a cost to the Government
The
and tests accomplished." Special emphasis wasiitolbeuplacedauponnvestigation
reporting: -(1) the knowledge gained regarding the combination of a
laser with a harmonic doubling crystal element as a source of coherent,
visible light radiation; (2) the data organized regarding the use of the laser
with a variety of photographic sensitized materials; and (3) recommendations
regarding the breadboarding and building of prototype equipment to
support the photo-exploitation community.
Evaluation
1. An entirely accurate appraisal of the worth of this contract
and its final report will be most difficult to make. Due to concurrent
advances in the state-of-the-art regarding lasers, several aspects
of the prescribed course of study became unavoidably obsolescent during
the contract period, while other features retained their original
significance throughout. In particular, the development of an operational,
.continuous wave, gas laser, which radiated in the blue-green wavelength
area virtually eliminated the necessity of resorting to the harmonic
doubling process with its consequent flicker fusion of discrete pulses
from the neodymium-doped, borate glass laser. In view of the above
unforeseen circumstances, it would be both unfair and inaccurate to
judge I work solely upon an absolute value basis. Their work
will be evaluated according to the successes and/or failures experienced
.in approaching their objectives as originally stated.
2. The final report does not reflect inputs from other sources
associated with similar studies; a literature search in the required
depth would have helped the study.
3. The laboratory-oriented portion of the study was a competent effort
as far as it went. Unfortunately, it was cut short by the unreported

re-allocation of equipment to another project during the re-examination
of the goals on this program. Prior to that time,Ohad successfully
completed the initial, mechanical problem-solving stage in achieving
operation of the glass laser with harmonic doubling element. Aside
from a theoretical error in some crystallographic considerations and the
consequent backtracking in experimental procedure, this phase of the
contract seems to have progressed well with some meaningful results. In
fact, its description occupies the bulk of the Final Report. Subsequent
to this phase were scheduled the photographic tests which promised to
yield the results of greatest potential interest to us. These tests,
involving image quality and a variety of sensitized materials, however,
were virtually eliminated by all because of rather tentative
findings obtained from PAR 21 The lone area to receive any detailed
attention was that of beam uniformity, only preliminary results were
obtained, however, and no significant quantitative parameters or probable
causes could be determined. That the beam would vary in spatial intensity
was expected; the correction of this phenomenon is a real photographic
concern and a known problem area.

generation of visible, coherent
radiation is valid. The necessity of such a high energy, low efficiency
method of lasing has become outmoded, however, and even at the time of
this contract, 0 sole recommendation that we expecta moderately
priced, continuous wave, blue-green, gas laser soon to be commercially
available was a foregone conclusion.

27 January 1966
I have received your letter of 3 January, together with its
attachment "NPIC Evaluation of PAR 211", dated 30 December 1965. Because
of the wording of this evaluation as well as your informal forwarding of
it, I am sure you do not desire a sentence by sentence commentary on it.
One of the misconceptions that came up early in the life of
this contract was that the services of our Research Laboratory were being
bought. I have tried in the past to make it quite clear that this Company
will not accept work under contract for any research involving photo-
sensitive materials or processes. We might attempt to determine, under
contract, what material, process, equipment or combinations of these would
best solve a customer problem. Nevertheless, this misconception continues
and you could go a long way in establishing rapport between us if you
could eliminate it.
I think I would disagree that the processing of the camera films
is not of interest to NPIC. Anything which affects NPIC's ability to
extract information from the film should be of importance to NPIC even
though they may not perform the operation in their own house.
It is true that we had planned to do work on the duplicating
films 8430 and 5427. In fact, in our report on 26 February 1965, we
indicated that we were ready to start work on these films. By this date,
however, we were not only close to our authorized expenditure but were
well aware of the feelings of your office concerning our efforts. The
stop work order, while formalized in a letter dated 27 April 1965, had
been implied in telephone calls and conferences much earlier. The three
supplements to this PAR were prepared as a result of specific requests
from your office but were not approved upon submission.
I am surprised that there is a complaint that the Final Report
includes data previously reported in quarterly and monthly reports. I
guess I just thought this was a common practise to collect all of the
data even though it might have been mentioned previously.
While your evaluators recognize the circumstances, they
apparently failed to realize that what they were reading was a "Termination"
rather than a "Final" report. We would be the first to agree that we had
not completed the job we had planned to do.
