Optical efficiency formula
WebP abs =−0.5 ω E 2 imag(ε) P a b s = − 0.5 ω E 2 i m a g ( ε) To calculate the absorption as a function of space and frequency, we only need to know the electric field intensity and the imaginary part of the permittivity. Both quantities are easy to measure in an FDTD simulation. Simulation setup Subscripts 1 and 2 refer to initial and final optical media respectively. These ratios are sometimes also used, following simply from other definitions of refractive index, wave phase velocity, and the luminal speed equation: where: ε = permittivity of medium, μ = permeability of medium, λ = wavelength of light in … See more This article summarizes equations used in optics, including geometric optics, physical optics, radiometry, diffraction, and interferometry.

WebIn simple situations (e.g., for some diode-pumped YAG lasers ), the slope efficiency is essentially determined by the product of the following factors: pump absorption efficiency the ratio of laser to pump photon energy (→ … WebThe wall-plug efficiency of a laser system is its total electrical-to-optical power efficiency, i.e., the ratio of optical output power to consumed electrical input power as measured at the wall plug. For example, if the optical output power of a laser is 5 W while its power supply consumes 100 W of electrical power, the wall-plug efficiency is 5%.
Webwhere h ν is the photon energy, η is the quantum efficiency, and e the elementary charge. For example, a silicon photodiode with 90% quantum efficiency at a wavelength of 800 nm, … WebWhile gold gratings that support only m = –1 and 0 orders typically achieve DE > 90%, they have the lowest efficiency of the three types primarily due to absorption of light in the gold. While metals can make excellent mirrors, there is always some absorption. Scattering can also play a role when the gold surface exhibits significant roughness.
