This pumping mechanism makes possible to attain. >>Invented in 1958 by Charles Townes and Arthur Schawlow of Bell Laboratories >>Was based on Einstein’s idea of the “particle-wave duality”of light. Laser light is emitted has wavelength of 633 nm (red), power in the range 0.5 to 50 mW; beam divergence about 1 mrad. N 1 to achieve the condition of population inversion between E 2 and E 1 at moderate pumping. ruby laser, Ti:sapphire laser, semiconductor laser. Looks like you’ve clipped this slide to already. Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation.The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.
