Abstract
An organic vertical-cavity surface-emitting laser is demonstrated, which is pumped by an InGaN-based blue laser diode. The vertical-cavity laser structure consists of a poly-N-vinylcarbazole film doped with Coumarin 540A and two Bragg reflectors made of TiO2/SiO2 quarter-wave thin films. By driving the pump laser diode with a pulse width of 3.5 ns, singlemode lasing was achieved at a wavelength of 540 nm for a threshold pump power of 137 mW/pulse.
