-1

的EnBOD样品具有最高的ASE效率

达到22.6%。其ASE主峰位于542 nm

阈值约为29.5 kWcm

-2

Abstract

Amplified spontaneous emission (ASE) properties of organic material EnBOD were studied under ultraviolet pulse laser pumping. EnBOD sample in dilute toluene solution shows narrow-band absorption and PL spectra

with the maximum peak located at 508 nm and 527 nm

respectively. The ASE efficiency changes with the solution concentration. The maximum ASE efficiency of 22.6% was obtained when the EnBOD sample concentration is 0.008 molL

-1

in which the ASE threshold is 29.5 kWcm

-2

ASE peak is 542 nm and full width at half maximum is about 12.4 nm. The ASE output intensity attenuated to 61.2% of the initial strength under the pulse pump frequency of 200 000. The results indicated that EnBOD is a kind of laser material with low ASE threshold and good light stability.
