Laser cooling is a quantum mechanical effect widely used by modern industries for temperature control at the molecular or atomic level. It is possible to cool an atom to a fraction of a degree above absolute zero. This effect is named after Sisyphus, a character of Greek mythology who rubbed the gods in the wrong way and was punished by Zeus for all eternity rolling a boulder uphill, but this task could never be completed by reaching the summit when the rock keeps slipping out and rolling back down again. In some sense, Sisyphus symbolizes the vain struggle of man in the pursuit of knowledge.
Although D. Jaque, J. Capmany, and J. García Solé (Spain) achieved radiations corresponding to the three fundamental colors (RGB) in solid states laser, it is the green laser that could hold the promise of reversing the greenhouse effect.
The wavelengths of green light are between 510 and 570 nanometers. At present, the laser devices that generate green are very inefficient compared to red and blue lasers with output power only in milliwatts which are ideally used as laser pointers in the classrooms, meetings, and conferences. However, the technique of frequency doubling could possibly be extended to frequency trebling, quadrupling, and higher powers such that by simply aiming the green Sisyphus lasers toward the sky all pockets of CO2 gas in the atmosphere will be cooled and made to fuse with water molecules forming organic sugar compounds.
