Lineshape and Strength of Two-Photon Absorption in an Atomic Vapor with a Resonant or Near-Resonant Intermediate State. J. E. Bjorkholm and P. F. Liao, Phys. Rev., 14, No. 2 (August 1976), pp. 751-760. We experimentally and theoretically consider two-photon absorption in a vapor with a resonant intermediate state. 

It is shown that maximum absorption rates and Doppler-free linewidths are simultaneously obtained. The experimental dependence of the lineshape and absorption rate upon mistuning from the intermediate state is in good agreement with theory. Photodecomposition in Popop Dye Vapor Lasers. P. F. Liao, P. W. Smith and P. J. Maloney, Opt. Commun., 17, No. 3 (June 1976), pp. 219-222. Experimental evidence is presented which shows that the premature termination of dye vapor laser gain observed in optical pumping experiments is due to photodecomposition. Addition of up to 4 atm of buffer gases was found to have little effect. 

A Tester Independent Program Language. R. P. Davidson, Digest of Papers: 1976 Semicond. Test Symposium (October 1976), pp. 76-77. An integrated circuit (IC) designer writes test procedures for his devices in tester independent format (TIF) without being required to have detailed knowledge of the target system. Test requirements are defined in terms of device pins, stimuli (i.e., current/voltage), and timing. A language translator converts this information to a test program for a target machine.
