A very high temporal resolution and a broad bandwidth are but two advantages provided by the use of extremely short sub-5-fs pulses in a nonlinear spectroscopic experiment. However, the applicability of the standard theoretical description becomes questionable for the pulses that consist merely of a couple of optical oscillations. Far instance, the conventionally employed slowly varying envelope approximation, implying that the change of the pulse amplitude on the duration of an optical cycle is negligible compared to the magnitude of the amplitude itself, can no longer be maintained. Furthermore, the phase-matching bandwidth that is limited due to dispersion in the nonlinear medium rapidly gains importance with the increase of the spectral width of the pulse. Another point of serious concern is the frequency-dependent variation in the sensitivity of signal photodetectors. In combination, these features result in what is known as a spectral-filter effect. Finally, artificial lengthening of the experimental transients is a direct consequence of the noncollinear geometry employed in spectroscopic experiments. We present a theoretical analysis which thoroughly reexamines the formalism of ultrafast photon echo spectroscopy. We obtain a general expression for the echo signal, which is valid even for single-cycle-pulse applications. The derived formalism is applied to photon-echo spectroscopy on the hydrated electron with 5-fs pulses.","PeriodicalId":250878,"journal":{"name":"Conference Digest. 2000 Conference on Lasers and Electro-Optics Europe (Cat.

Experimentally validated rigorous microscopic many-body calculations of semiconductor gain and refractive index spectra for a wide variety of quantum well structures provide the foundation on which we build a full scale space-time interactive simulation model of both low and high power semiconductor lasers. The simulation model is extremely flexible utilizing look-up tables generated for a particular QW structure with confinement barriers (GRINSCH, SCH). The ability now exists to design and optimize laser structures starting from the same level as the materials grower. We explicitly illustrate the occurrence of dynamic intensity filamentation in high power laser diodes and discuss the means to suppress such behavior using current/index profiling, cavity spoilers, flared contacts etc. As an illustration of low power instabilities, we discuss the stimulation of isolated multi-longitudinal mode beatings in the presence of an external feedback mirror, power dropouts in DFB and regular lasers and synchronization of high dimensional chaotic oscillations between a transmitter and receiver laser system.","PeriodicalId":250878,"journal":{"name":"Conference Digest. 2000 Conference on Lasers and Electro-Optics Europe (Cat.

Selecting from but a handful of commercially available laser crystals, laser designers have produced an impressive array of solid state lasers able to perform a wide range of scientific, industrial and military applications. Laser design possibilities were enormously expanded with the development in the late 1980's of efficient bright, and powerful semiconductor laser diodes as pump sources for solid state lasers. Despite this, it sometimes proves difficult, if not impossible, to design lasers meeting some applications requirements, when drawing only on presently commercially-available laser crystals, especially when particularly demanding size, weight, and efficiency requirements are imposed. Thus, there continues to be a need to identify, characterize, and develop novel laser crystals possessing characteristics that significantly broaden design options for future laser devices and systems. Because the cost is rather large to transition a newly discovered optical material from laboratory experiments to commercial readiness, it is necessary that such materials possess significantly distinct and enabling characteristics, relative to available materials, and that the intended application(s) be sufficiently highly valued. Fortunately, since the discovery of the laser /spl sim/40 years ago, an extensive array of modeling tools, device design experiences, and material property data bases have evolved, which can be exploited to guide the search for applications enabling new laser materials. By way of example, the author considers in detail the search leading to the discovery of the new class of room-temperature, diode-pumped, tunable mid-IR lasers based on tetrahedrally-coordinated, divalent 3d-transition metal ions in II-VI chalcogenide crystals.","PeriodicalId":250878,"journal":{"name":"Conference Digest. 2000 Conference on Lasers and Electro-Optics Europe (Cat.
