Summary |
| |
In this lecture, you have been introduced to lasers. The principles of laser action and the working of gas lasers, solid state lasers and dye lasers was outlined. The laser could also be classified in terms of the number of levels involved in laser action. Chemical applications of lasers such as isotope separation and spectroscopic applications were described. The attainment of state selectivity through laser pulses was illustrated for the reaction between C6H6 and BCl3. A few technical details about lasers were outlined in the later part of the lecture. The methods used for obtaining pulses of very short duration were also elaborated. For more details, you need to consult detailed technical books in the subject. (see references cited at the end of the module. The use of the pump-probe technique to study ultrafast relaxation processes was illustrated towards the later part of the lecture. |
