What is the gain material and its phase, typical pumping method, typical output power, and efficiency for laser of your choice producing tunable visible light?

Expert Solution

Gain Material and its phase :

* If the higher energy state has a greater population than the lower energy state, then the light in the system undergoes a net increase in intensity. And this is called population inversion. But this process cannot be achieved by only two states, because the electrons will eventually reach equilibrium with the de-exciting processes of spontaneous and stimulated emission

Typical pumping method :

When photon of blue green light incident on Ruby crystal,electrons on ground state absorb on excited and jump on higher energy state levelsand comes back to metastable state. They increase population of electrons in metastable state . This process is called TYPICAL PUMPING METHOD.

Typical output power :

Typical output power vs drive current for LED and laser diode . The LED has a more linear output power that makes it suitable for analog power modulation . Typical applications are Local area network,Closed circuit tv , and transmitting information in areas
