Studies of new organic molecules and hybrid systems for lasing applications

We present experimental results of studies of new organic compounds and hybrid systems which can be used for amplified spontaneous emission (ASE) and lasing applications. As dye molecules we have choose group of pyrazoline derivatives (PRD). Luminescence has been studied for solution of PRD in tetrahydrofuran. ASE has been studied for thin films of PRD in polymethyl methacryalte matrix. For the samples excitation we have used Nd:YAG nanosecond pulsed laser doubled in frequency (λ= 532 nm). We report on light amplification and spectral dye luminescence narrowing in function of different excitation pulse energy densities.
