Increasing the average power of broadband, few-cycle terahertz (THz) sources is currently a topic intense investigation, fueled by recent immense progress in high femtosecond laser driving at 1030 nm. However, many crucial applications would benefit not only from an increase power, but also ultra-broad bandwidth, while maintaining dynamic range these frequencies. This calls for challenging combination repetition rates and simultaneously. Here, we discuss promising approach enabled organic crystals THz-generation. Specifically, this review article discusses advances with most commonly used BNA, DAST, DSTMS, OH1 HMQ-TMS. We place special emphasis on nonlinear thermal properties future directions field.
