We report a highly efficient, compact low-cost tunable dye laser pumped directly by green laser diodes. A tunable dye laser quasi-longitudinally pumped by two multimode InGaN diodes (520 nm), was implemented in a 200 ns pulsed mode with a 2 Hz repetition frequency. The lasing threshold energies were found to be 0.23–0.37 μ J using an output mirror with 13[%] transmission. The best efficiency at the lasing maximum for Pyrromethene 567 exceeded 25[%] when the slope efficiency in broadband cavity configuration was 43[%] at an absorbed pump energy of 0.75μJ. The laser overlapped a wide spectral region of 145 nm (from 537 to 682 nm) with a linewidth of 1 nm. This indicates that green diodes can be used as an effective pump source for tunable dye lasers. Such lasers will be useful for spectroscopy, medicine and other fields due to their compactness and low cost. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.
