Effects of magnetic field and optical fluence on terahertz emission in gallium arsenide
The excitation density dependence of magnetic-field-enhanced terahertz (THz = 1012 Hz) emission from (100) GaAs is studied. It is found that THz power saturates at a higher optical-excitation density, when a magnetic field is applied. This observation explains the different magnetic field enhancemen...
