Document Type: JOURNAL ARTICLE Most documents available from AIAA Technical Library Journal Announcement: IAA8508 Dynamic interferometry is used to show that the radiation of a super1uminescent parametric oscillator with a LiNbO3 crystal pumped by the second harmonic of a picosecond YAG:Nd(3+) possesses both rapid-chaotic and slow- quadratic modulation. Transmitting the radiation from the optical parametric oscillator (DPO) through an anomalous-dispersion system with a diffraction gratitng yielded a five-fold reduction of the pulse duration. It is suggested that the low energy conversion efficiency of the 0P0 with the LiNbO3 crystal is due to linear frequency sweep, stimulated Raman scattering, and biphoton absorption. (L.

Fabrication of the best antennas arrays was made more facile with finding that increased argon flow during the de sputtering produced more uniform bismuth films and bonding to antennas must, be done with the substrate temperedre below 100 C. Higher temperatures damaged the bolometers. During the testing of the antennas, it was found that the
