A laser from a living cell

In the OPN journal there was published a short note about the laser from a living cell. The cell was genetically engineered to produce a green-glowing jellyfish protein. Then the cell was placed between two reflectors.

In such a setup the cell acts as the laser's gain medium. When pumped with a brief burst of blue light, the proteins fluoresced, generating light that bounced back and forth between the reflectors, gaming more energy with each pass through the cell.

By the way, from the OPN journal again, the table of lasers and their power:



Quite nice.
