“…Since the average power of the rod laser scales with the length of the rod, side pumping offers higher average power possibilities than end pumping. This has been confirmed by Kasinski et al 86 who demonstrated a lOW average power Q-switched laser with a scaling potential to greater than lkW of average power. Side pumping of slab geometry lasers offers scaling to high average power levels because the power scales as the area of the slab.…”

“…If the beam is focussed by means of a lens of focal length f, a focal spot is formed at a distance x from the lens. In a good approximation, the distance can be calculated using geometrical optics x = ft (1_f/R*) (6) As the input power is increased the radius of curvature R* will change resulting in a shift of the longitudinal focal spot position. This shift of the focal spot can be reduced by expanding the beam before focussing.…”

Different unstable resonator schemes are described, taking into account that the laser rod acts like a varying thermal lens. The single rod resonators can be extended to contain two or three rods. With l5Omm*lOmm Nd:YAG rods, the presented resonator designs were investigated experimentally. Output power and beam parameter products as well as the influence of the thermal lens on the focusability were measured. The sensitivity of output power and beam steering to mirror tilt is presented and the design of the variable reflectivity mirrors is described.

“…After 7 cm in air, such droplets normally exhibit clearly visible lateral motion [Qian et al, 1992]. Laser-pointing instabilities are also well known and expected to be significant [Kasinski et al, 1992]. The effect of the large pump beam diameter and these lateral beam and droplet motions prohibit selective mode excitation using pump beam translation alone.…”

When ZAA applied MDSRS to VOAG-generated water droplets, they found that the relative heights of the water 3245 cm -l and 3450 cm -1 Raman bands were different from a reference bulk water sample. These differences were interpreted by ZAA as resulting from VOAG-induced hydrogen bonding changes occurring in the water droplets. Hydrogen bonding ratios, as defined by ZAA and normally having a value of 0.95, were reported to have decreased to 0.56. Since most currently accepted mass accommodation coefficients on aerosols were measured using VOAG technology, ZAA conclude that such values are invalid. This claim has such wide ranging implications that it required critical review and experimental confirmation from other laboratories.This paper is not subject to U.S. copyright. Published in 1996 by the American Geophysical Union. Paper number 96JD02158.This comment is divided into four sections. First, we discuss possible systematic spectral artifacts which could appear under operating conditions used by ZAA. Second, we describe VOAG experiments in which we perform a similar spectroscopic study under conditions that avoid the aforementioned problems. We find that there are no changes in Raman spectra, either between the surface and the droplet interior or between droplet and a bulk liquid reference sample. Third, we critically examine the validity of several of the VOAG-related mechanisms the authors have proposed. We show that these cannot lead to extensive changes in the hydrogen bonding ratio as reported. 23,053
