Incoherent Fourier transform spectroscopy with room-temperature coverage from NIR to THz
Jakub Mnich, Grzegorz GomóÅka, Marco Schossig +2
Despite the broadband nature of thermal light sources, optical spectroscopy over multiple spectral bands simultaneously remains challenging. Here, we demonstrate a practical Fourie…
Pulse duration retrieval using a commercial laser diode with a monitor photodiode
Adrian F. Chlebowski, Lukasz A. Sterczewski, Jaroslaw Sotor
Semiconductor lasers merge coherent light emission with photodetection and, owing to third-order nonlinearities in their active region, function as sensitive room temperature two-p…
Sensitive and accurate femtosecond pulse characterization via two-photon absorption in Fabry-Pérot laser diodes
Adrian F. Chlebowski, Jakub Mnich, Lukasz A. Sterczewski +1
Semiconductor lasers offer native bifunctionality enabling coherent light emission and linear photodetection. They can also operate as sensitive two-photon absorption detectors due…
Broadband THz wave generation and detection in organic crystal PNPA at MHz repetition rates
Lukasz A. Sterczewski, Jakub Mnich, Jaroslaw Sotor
Organic nonlinear optical (NLO) crystals have emerged as efficient room-temperature emitters of broadband THz radiation with high electric field strengths. Although initially confi…
