Luminescent Concentrator Pumped Organic Laser

A new approach towards low threshold organic lasers has been demonstrated by our group. The above image is the Luminescent Concentrator pumped organic laser. The application of the thin film luminescent concentrator (green film on the left) can effectively reduce the lasing threshold of the attached organic semiconductor laser (red piece of glass on the right) by a factor of 5. The red cross pattern on the right shows the lasing beam emitting from the organic laser. This work has been featured as an 'Advances in Advance' in Advanced Materials and can be viewed here.
