We have developed a simplified version of the side-pumped pulsed dye laser which has a spectral halfwidth of 1.25 GHz and a peak power of 10 kW at 600 nm. The basic laser consists of only four components (output mirror, dye cell, diffraction grating, and tuning mirror) and is exceptionally easy to align. Since the beam expander has been eliminated, the laser cavity can be made quite compact ...

Abstract. We study the pulsar timing, focusing on the time delay induced by the gravitational field of the binary systems. In particular, we study the gravitomagnetic correction to the Shapiro time delay in terms of Keplerian and post-Keplerian parameters, and we introduce a new post-Keplerian parameter which is related to the intrinsic angular momentum of the stars.

The Keplerian telescope may be the easiest beam expander one can build. For this configuration, two plano-convex (convergent) lenses are arranged so that the distance between them is equal to the sum of their focal lengths. The focal point of the combined system will be in the gap between the lenses.

Larger values of the beam divergence angle apply if the beam profile is other than a truncated Gaussian. The beam divergence angles associated with other beam spatial profiles (see Section 2.C) are larger than the value given by Equation (2.6). In many practical cases, lasers with relatively low output power will emit diffraction-limited beams.
