WebWhat is Gain? Gain is a measurement of the reflectivity of any screen or projection surface. The gain number represents a ratio of the light that is reflected from the screen as … WebFigure 4 shows that, although it basically works, gain guiding initially makes the laser beam substantially smaller than the resonator mode as …
WebGuiding requires a strong pump field and high beam current. The beam filling factor is considerably enhanced by the guiding. These studies were done for optical guiding under conditions where the refractive guiding effects dominate over the gain guiding effects (previous studies by others chiefly explored the gain-guiding limiting case).
