“…Charge transfer mechanism induced by laser during ion-atom collisions have central place in plasma physics. Several studies are done to explore its importance [35,36,37,38]. Collisional rotational dynamics of NO(X 2 π)+Ar sytem has been investigated theoretically and experimentally [40].…”

We review on the theoretical status of intense laser orientation and alignment-a field at the interface between intense laser physics and chemical dynamics with the potential applications ranging from high harmonic generation, nano-scale processing and control of chemical reactions. The evolution of the rotational wave packet and its dynamics leading to orientation and alignment is the topic of the present discussion. The major part of the article basically presents an overview on recent theoretical progress in controlling the orientation and alignment dynamics of a molecule by means of shaped laser pulses. The various theoretical approaches that lead to orientation and alignment ranging from static electrostatic field in combination with laser field(s), combination of orienting and aligning field, combination of aligning fields, combination of orienting fields, application of train of pulses etc. are discussed. It is focussed that the train of pulses proves to be quite efficient in increasing the orientation or alignment of a molecule without causing the molecule to ionize. The orientation and alignment both can occur in adiabatic and non-adiabatic conditions with the rotational

The laser performance of coumarin 440 (C440) and coumarin 460 (C460) mixture is studied. The mixture dyes demonstrated broader and more efficient tuning curves compared with those of coumarin 440 and coumarin 460. A wide tuning range from 421 nm to 482 nm is achieved. The highest conversion efficiency of 12.2% is obtained at 453 nm. Comparing with the efficiencies of individual dye C440 and C460, which are ∼5%, the tuning range and the conversion efficiency of the coumarin 440 (C440) and coumarin 460 (C460) mixture are the best under the same condition so far. All our results indicate that high laser performance can be achieved using the co-doped laser dyes of coumarin 440 and coumarin 460.

“…The laser-induced collisions leading to energy transfer is an optical process where the laser field is applied during the collision between the two particles which could be the combination of ion with atoms or molecules [1][2][3][4][5][6][7][8], atom with atom [9][10][11] etc. The laser-induced collision was proposed in the 1970s [12,13].…”

Rotational Excitation of Diatomic Molecule: Time Dependent Study

2018

View full text Add to dashboard Cite

Recent experimental evidences have prompted us to study the dynamics of laser-assisted rotational excitation of a diatomic molecule due to an ion impact. The collision time between the ion and the molecule is very small (few atomic units) and the laser pulses considered are of picosecond range. We study the evolution of the rotational probabilities by varying the various laser parameters (pulse shape, field strength, pulse width, frequency) and collision parameters (impact parameter b, collisional velocity v). It is found that the probabilities of the rotational states depend strongly on the laser pulse parameters and the collision parameters. The study is more emphasised by studying J 2 (a parameter defining the extent of the rotational excitation) and Jz for the system under concern. For higher value of b, the maximum value obtained by J 2 increases and vice versa. Also, the molecule enters the transient mode for large b and v.
