A dendrimer was used to modify the laser dye and increased its concentration up to 4.95wt. % in the photocured resin. The DFB resonator was fabricated by using two-photon induced polymerization (TPIP) technique. The ASE at 556nm was observed with a threshold of 0.30μJ/pulse due to fourth-order diffraction feedback of the optical gain. This DFB could be expected to open a way for the fabrication and application of microscale polymeric mirrorless laser.
