Abstract :
A compact, easily tunable terahertz burst emission system based on the mixing of two linearly chirped pulses in Michelson interferometer was investigated. The use of linearly chirped optical pulses ejected straight from the picosecond fiber laser enabled us to avoid bulky external optical pulse stretching schemes. System operation range determined from the power measurements reached up to 2.4 THz.
