A general diffraction analysis is presented to determine the irradiance distributions produced by the interference of diffracted wavefronts from multiple pupil configurations. Specifically, interference phenomena in the geometrical shadows of the Fre

Intensity mapping aberrations for high average power laser beams are examined from the point of view of diffraction theory. For the Fresnel ripple aberrations, it was determined that indeed they behave like a circular diffraction grating where energy

Using Fresnel diffraction integrals, calculations have been made of the irradiance and power distributions in the near field and in the vicinity of the focus for Gaussian beams focused through annular apertures. Universal curves have been plotted whi

We examine the linear electrodynamics arising from ion-atom collision-induced absorption. For this situation, induced absorption is achieved by means of long-range electrostatic forces, and the resulting spectral lines are relatively intense, symmetr

We examine the wave equation for an open resonator with flat mirrors in the case in which it is driven by a nonlinear gain term and formulate an integral equation from first principles. The eigenvalues and eigenfunctions of such a resonator equation

Summary form only given. The small quantum defect of Yb:YAG and the concomitant reduction in thermal lensing and birefringence relative to Nd:YAG makes these lasers attractive as potential high power, high brightness radiation sources, such as requir

Advanced Solid State Lasers.
Diode-pumped Yb:YAG lasers are of particular interest for high average power applications due to the reduced heat generation relative to Nd:YAG and the availability of high-power InGaAs laser diode arrays.

We describe a diode-pumped Yb:YAG laser that produces 1080 W of power cw with 27.5% optical optical efficiency and 532 W Q-switched with M(2)=2.2 and 17% optical-optical efficiency. The laser uses two composite Yb:YAG rods separated by a 90 degrees q

We have fabricated a diode-array end-pumped Yb:YAG rod laser with output powers greater than 200 W cw and 195 W Q -switched at 5 kHz. At an output power of 183 W and a repetition rate of 5 kHz, the beam quality was measured to be M(2)=2.4 . The laser

The vibrational and rotational temperatures in the supersonic flow of a gas‐dynamic laser have been determined simultaneously by using spectral gain measurement techniques (over a number of rotational lines). The vibrational and rotational temperat
