An organic semiconductor laser, simply fabricated by UV‐nanoimprint lithography (UV‐NIL) , that is pumped with a pulsed InGaN LED is demonstrated. Molecular weight optimization of the polymer gain medium on a nanoimprinted polymer distributed feedback resonator enables the lowest reported UV‐NIL laser threshold density of 770 W cm −2 , establishing the potential for scalable organic laser fabrication compatible with mass‐produced LEDs.
