In the example above, we established the equivalence of the geometric optics and modal analysis for the total, guided power excited in a weakly guiding, step-profile fiber by a totally incoherent source when the fiber parameter F-> 00. To determine the error in the geometric optics analysis when V is... 

The local-mode fields are orthonormal, and consequently the total guided power propagating in the positive z-direction follows from Eqs. (11-16), (11-27) and (28-1) as... 

Beyond certain limits increase of the reflux ratio does not appreciably increase the separating power or efficiency of the column. As a rough guide, if the column has an efficiency of n plates at total reflux, the reflux ratio should be between 2>t/3 and 3n/2. 

Fig. 3.10. Normalized ELM particle loss (AArELM/Artot, where Ntot is the total particle content) versus ELM frequency (/elm) for JET discharges with plasma current /p = 2.5 MA, toroidal field Bt = 2.4-2.7 T, input power Pinput = 14-17 MW and medium (S = 0.3) and high (<5 = 0.5) triangularity. Two discharges (at medium and high S) in which Argon has been injected to increase the level of plasma radiation are shown for comparison. Lines are to guide the eye [16]...

The installation comprises laser emitter, laser power-supply unit, water-air cooling system and guiding computer. Total weight of the installation is 40 kg consumed power is 3 kW from power network 220 V. The installation capacity reaches to 2 m per hour the distance from emitter to surface to be decontaminated can attain 1.5 m. Laser emitter is installed at a remotely operated rotator. 

Figure 2. A - Experimentally measured and theoretically calculated values of dns/dt, the number of Stokes photons per unit time emitted from the atomic vapor cell. For each plot, ns = f dt dns/dt represents the total number of photons emitted from the cell. The write laser power is varied from 25 mW to 100 mW. B - Experimentally measured and theoretically calculated values of dnAs/dt, the number of anti-Stokes photons per unit time emitted from the atomic vapor cell. The experimental pulse shapes correspond to a Stokes pulse with ns 3 photons, and the theoretical curves assume an initial spin wave with nspin = 3 excitations and an optical depth of 20. Each curve is labeled with the power of the retrieve laser. Inset theoretical calculation of the number of flipped spins per unit length dnspin/dt as a function of position in the atomic cell, for nspin = 3. C - Measured anti-Stokes pulse width (full-width at half-maximum) and total photon number as a function of the retrieve laser intensity. Lines are intended only to guide the eye.
