“…The optical output from the AR coated facet is collimated using an aspheric lens (A 1 ) and directed towards the output coupler (OC), which provides feedback and completes a resonator with a fundamental repetition rate of 383.1 MHz. The output is amplified with a tapered amplifier (TPA) as used in [10] and subsequently compressed by a single pass Martinez type compressor formed by grating G, achromatic lens AC and mirrors M 1/2 [11]. After each active component, i.e.…”

“…One method to process the large bandwidth is to use the subsampling radar principle by means of asynchronous optical sampling (ASOPS) [4]. Two modelocked laser diodes functioning as pulse generators are operated at slightly offset repetition rates so that they can be used to sample each other [5]. Thus, the obtained IF signal is stretched in the time domain, allowing digitization at moderate frequencies.…”

“…Proof-of-principle demonstrations have shown the feasibility of integrating diode lasers into asynchronous sampling THz-TDS systems [4,5]. The generated pulses from utilized lasers, realized either with an external cavity or monolithically, are shown to be compressible into subpicosecond range.…”
