Abstract/OtherAbstract:
|
We studied the effect of pressure variation on intrapulse Raman scattering for a single-cycle and few-cycle pulses in a gas cell of a given length filled with gaseous deuterium, in the framework of a new model equation that goes beyond the slowly varying envelope approximation. We show that, for a single-cycle pulse, pressure variation does not have any influence on the pulse spectrum. On the other hand, for a four-cycle pulse, an increase in pressure considerably affects the pulse spectrum and leads to substantial broadening and blueshift of the output pulse spectrum. Also, with increasing pressure, more and more energy is transferred from the red to the blue components. |
