Abstract :
We present a novel technique to generate a continuous, broadband terahertz spectrum with non AR-coated laser diodes. The combination of two spectrally controlled diode lasers and the use of their combined output in a terahertz cross-correlation spectroscopy setup results in signals principally comparable to that of femtosecond pumped TDS systems.
