In many ways, the physics of laser and the universe are analogous. The root of the analogy is the fact that both laser and early universe depend completely on the quantum nature. We have also presented a simple analogous example of the growth of a flower at successive stages of development and shown how the arrow of time may be represented in these cases.展开更多

The red florescence is most prominent when excited with broad band source like 30 mW green or blue solid state laser, but the acetone extract of plant leaves Allocasa cullcuta schot unusually exhibits the strong intensity in the red sector of the spectrum. A dark room can be easily illuminated with this red radiation. We have used this fact to explore a possible realization of chlorophyll laser which would be a natural environmental phenomenon.展开更多
