Abstract
Luminescence of Nd3+ is observed in a new undeuterated organic liquid medium. The measured lifetime 'tau' of 1060-nm emission is 460 microseconds and the emission cross section is 2.54*10^(-20) cm2. According to the spectral research results, two pumping schemes are designed and the threshold energies for outputting laser are roughly calculated. Taking 808 nm as pumping wavelength and using single-pulse-mode pumping, the threshold pumping energy of single pulse is evaluated about 250 mJ to ensure the pumped volume enough large and so the peak power of 200-microsecond pulse is about 1250 W, which is easily obtained today. The rough estimated results prove that this organic solution is a successfully potential laser media.
