  • Transient absorption spectrometer using excitation by pulse current
    Patent number: 12644843
    Abstract: A transient absorption spectrometer using excitation by a pulse current, including: a central control unit; a pulse generator configured to generate a current pulse signal under an action of a first trigger signal sent by the central control unit, where the current pulse signal is applied to a sample to be tested such that the sample is in a non-luminous excited state for single-carrier injection or a luminous excited state for luminescence in which an electroluminescent signal is generated; a laser configured to emit a pulsed optical signal under an action of a second trigger signal sent by the central control unit; a beam splitter disposed in a light-exiting direction of the laser, and configured to split the pulsed optical signal into a detection optical signal and a reference optical signal, where the detection optical signal irradiates the sample to be tested to generate a detected optical signal; a data acquisition unit configured to acquire, under an action of a third trigger signal and a fourth trigge
