Spectroscopic properties and amplified spontaneous emission of a new derivative of fluorescein

Photo-physical properties and amplified spontaneous emission of a new derivative of fluorescein

“…For comparing the characteristics of photobleaching for AXBE with AXOBE in our previous work [26], we used the normalized photostability method [36]. The normalized photostability for AXBE and AOXBE solid samples were calculated as 0.11 GJ/M and 0.17 GJ/M, respectively.…”

“…The amplified spontaneous emission (ASE) efficiency and photostability of the covalently bonded dye with the polymeric chain have been measured using the experimental setup in our previous work [26]. The dye laser rod is transversely pumped by 355 nm of third harmonic Nd-YAG laser (Continuum PL7010) with 5 mJ, 8 ns pulses at a repetition rate of 5 Hz.…”

“…[26] was as follows: (1 Â 10 À3 M) (2.5 mg) of the dye was dissolved in the required amounts of the two freshly purified HEMA and MMA monomers. The resulting mixture were placed in an ultrasonic water bath for 10 min until monomer-dye was completely dissolved.…”

Optical, Photophysical, Stability and Mirrorless Lasing Properties of Novel Fluorescein Derivative Dye in Solution

“…Depending upon these results and trying to find novel laser dye with high laser performance and photostability, we carried out our previous work [32,33] and are now dealing with new fluorescein derivative. The present investigation deals with synthesis, chemical structure confirmation by spectroscopic techniques, photophysical properties, optical properties, stability and amplified spontaneous emission efficiency were determined and compared with the parent fluorescein itself.…”
