The conjugated polymer laser with temperature-controlled power output uses a triphenylamine dimer-based conjugated polymer as the laser medium to produce an output laser beam having a beam energy tunable between approximately 20 J and approximately 325 J over a temperature range of the triphenylamine dimer-based conjugated polymer between approximately 40 C. and approximately 85 C. The triphenylamine dimer-based conjugated polymer laser medium is a solution of poly[N,N-bis(4-butylphenyl)-N,N-bisphenylbenzidine], known as poly-TPD(4B), dissolved in toluene. Poly-TPD(4B) has a long side chain of butyl (C.sub.4H.sub.9), providing temperature-dependent dimerization, which may not be found with shorter chains of butyl, such as in poly-TPD(4E) or poly-TPD(4M). The molar concentration of the poly-TPD in the solution is between approximately 5 M and approximately 100 M. Additional adjustable tuning of the molar concentration of the poly-TPD in the solution provides for wavelength tuning of the output laser beam between approximately 415 nm and approximately 445 nm.

A device for creating an optic pulse with different wavelengths separated by time. A pump laser is configured to output energy to a dye cell which, responsive to the energy, outputs an optic pulse. Mirrors direct the optic pulse away from the dye cell towards a spectrograph. The spectrograph has an input and two or more outputs. The spectrograph receives and converts the optic pulse to a wavelength separated optic signal presented on the two or more outputs. A first optic cable has an input end and an output end. The input end receives a first output from the spectrograph. A second optic cable has an input end and an output end. The input end receives a second output from the spectrograph. The second optic cable is a different length than the first optic cable to establish a time shift between the signals exiting the first and second cable.
