| Abstract: | Femtosecond time-resolved fluorescence non-collinear optical parametric amplification spectroscopy(FNOPAS) is a versatile technique with advantages of high sensitivity, broad detection bandwidth, and intrinsic spectrum correction function. These advantages should benefit the study of coherent emission, such as measurement of lasing dynamics. In this letter,the FNOPAS was used to trace the lasing process in Rhodamine 6G(R6G) solution and organic semiconductor nano-wires.High-quality transient emission spectra and lasing dynamic traces were acquired, which demonstrates the applicability of FNOPAS in the study of lasing dynamics. Our work extends the application scope of the FNOPAS technique. |
