“…Hill et al [66][67][68] have studied in detail the ultrashort laser pulse interaction between the ground state and one excited electronic state in order to elucidate photodissociation dynamics of excimer molecules. Their system consists of two electronic states: Upper electronic PEC ͑harmonic potential͒ and lower linear potential.…”

A theoretical study of the low-lying excited electronic states of thiocarbonyl chlorofluoride and their dissociation pathways Time-dependent quantum mechanical study of photodissociation of molecular oxygen in the Schumann-Runge continuumWe have theoretically studied the usefulness of ultrashort chirped laser pulses for laser control of photodissociation dynamics with a one-dimensional model system involving a potential well in the excited electronic state. The molecular system we treat in this paper entails three electronic states, a ground electronic state, and two excited electronic states. The ground electronic state is radiatively dipole-coupled with the lower of the two excited electronic states, while the two excited electronic states are themselves connected by diabatic coupling potential. Previously, we found a single linearly chirped ultrashort ͑in the order of fs͒ laser pulse can be employed to control photodissociation dynamics according to the sign of the chirp rate: A positively chirped pulse traps the molecule in the excited state potential well, while a negatively chirped pulse photodissociates the molecule rapidly. In the present paper we take into consideration the influence of the strength of the diabatic coupling and the reduced mass of the molecular system and show such a selectivity works best when the diabatic coupling is moderate and the molecular system is light. We explain these phenomena by a state selective excitation in vibrational states under the condition of adiabatic rapid passage ͑ARP͒ population transfer. We solve the integrodifferential equation of the molecular system involving the vibrational states explicitly, which is a quite different approach from that for the atomic case.

“…coherence time represents a temporallag between the induced polarization and the electric field, coherence effects play an important role in limiting the magnitude and width of optical pulses [16,17,19,23,28,29]. However, when the optical pulse width is long compared to the coherence time, the rate equation approximation (or zero coherence time approximation 깐 = 0) is often used.…”

“…However, the studies on synchronously pumped mode-locked dye lasers [16,19,20] have shown that inclusion of coherence effects is essential to understanding the dye laser dynamics when the cavity length mismatch is very small. Coherence eff농 cts were also found to be significant for understanding ultrashort pulse evolution in excimer lasers [21][22][23][24]. As the optical p비 ses produced or amplified by dye lasers become shorter and shorter, coherence effects are expected to be more substantial.…”

Single amplified ultra-short laser pulse is very important in basic scientific researches as well as in ultra-high power laser applications. The high intensity ultra-short laser pulse usually comes from the mode-locked pulses train. It is important to develop a laser amplifier configuration that can optimally amplify single ultra-short laser pulse. We present in this research, first by controlling the synchronization of the amplifiers chain, and then optimally adjust the shape of amplified spontaneous emission of each amplifier, we can select the single amplified ultra-short laser pulse out of the seed ultra-short pulses train and boost the laser pulse to the maximum power amplification. An adjustable repetitive single pulse high intensity ultra-short pulse UV laser system was developed and the laser outputs were extracted at various ends and characterized in detail.
