Abstract :
Composing a thin film by spin-coating dye-doped organic monomer onto a glass substrate under UV irradiation to be polymer, DFB laser operation is achieved using side pumping of an interference pattern of pump beam. The thin film consists of Rhodamine B (Rh-B)-doped thio ether methacrylate (TEMA) with the thickness of ∼2 μm. Periodic gain structure is induced by using irradiation of the interference pattern of Nd:YAG (SHG) 532 nm pulsed laser. The lasing output is then obtained near 610 nm. Effects of the gain profile induced by pump beam on the lasing output are also described.
