1.6.2 Pure Polymer Lasers
Lasers based on neat and dilute blends of conjugated polymers are listed in Table 1.6.1.
All experiments involved pulsed excitation and were performed at room temperature. The
reported observations may be indicative of lasing or amplified spontaneous emission. The
lasing material, solvent used, mode of photon confinement, and lasing and optical pumping
wavelengths are listed together with the primary reference. For lasers that have been tuned
over a range of wavelengths, the tuning range given is that for the experimental configuration
and conditions used and may not represent the extremes possible. The references should be
consulted for this information. The references should also be consulted for details of the
chemical composition and molecular structure of the lasing compounds.
