Novosibirsk terahertz free electron laser: Facility development and new experimental results at the user stations

The Novosibirsk FEL (NovoFEL) generates tunable monochromatic coherent radiation as a continuous stream of 100-ps pulses with a repetition rate of up to 11.2 MHz and average power of up to 500 W. After commissioning of the second laser resonator in 2010, the spectral ranges of 120-240 μm and 40-80 μm are available to users. A review of experimental results for the past year is given.
