“…Recently, the generation of 200 fs pulses has been reported for a system similar to that shown in Fig. 9 [76]. The use of shorter pulses in the THz-TDS system promises the achievement of higher THz bandwidths.…”

We discuss different concepts for generating terahertz (THz) radiation with semiconductor diode lasers. Photomixing enables the generation of continuous wave THz radiation by difference frequency generation of two lasers or of two-colour lasers. Pulsed THz radiation for time domain THz spectroscopy is generated with modelocked diode laser systems including amplification and chirp compression. Finally, we analyse the concept of quasi time domain spectroscopy based on broadband diode laser systems.

“…The use of MLLDs with dispersion-compensated external cavities was reported to increase the spectral bandwidth, but not to reduce the pulse duration. In these reports, femtosecond optical pulses were finally obtained only by compressing the optical pulses using dispersion-compensating optics [9].…”

Abstract:We investigated the spectral and temporal characteristics of blue-violet femtosecond optical pulses generated by a passively mode-locked GaInN laser diode in a dispersion-compensated external cavity. The output optical pulses at 400 nm were analyzed in detail by intensity auto-and cross-correlation measurements using second harmonic generation on the surface of a β-BaB2O4 crystal. The obtained results clarified wavelength-dependent chirp characteristics of the optical pulses. The analysis suggested that a large frequency shift due to saturation in the saturable absorber and gain sections played an important role in the generation of femtosecond optical pulses.

“…The obtained pulses were almost unchirped. It should be noted that these unchirped pulses were obtained only by the use of spectral filtering, and without the need for the external pulse compressors commonly used for femtosecond pulse generation from MLLDs [10][11][12].…”
