研究目的
Investigating the generation of second harmonic radiation by a circularly polarized laser beam propagating in plasma with an obliquely applied magnetic field.
研究成果
The study demonstrates the possibility of generating circularly polarized second harmonic radiation by a laser beam propagating in plasma embedded in arbitrarily oriented magnetic fields. The amplitude of the harmonic radiation increases with the obliqueness of the applied magnetic field, with right circularly polarized laser beams yielding greater amplitudes than left circularly polarized ones under certain conditions.
研究不足
The study is theoretical and analytical, focusing on a mildly relativistic regime. Experimental validation and application in higher relativistic regimes are potential areas for optimization.
1：Experimental Design and Method Selection:
A perturbation scheme is used for evaluation of transverse components of current density in a mildly relativistic regime.
2：Sample Selection and Data Sources:
The study involves a circularly polarized laser beam propagating in plasma with an obliquely applied magnetic field.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The current density oscillating at twice the fundamental frequency of the laser field drives the second harmonic radiation.
5：Data Analysis Methods:
The amplitude of the circularly polarized second harmonic radiation is derived and its variation with obliqueness of the applied magnetic field is graphically depicted.
