Laser Physics and Laser Techniques.
1977Abstract : Substantial improvements have been made in the performance of the optically pumped 546.1 nm Hg laser. DC-pumped operation of sealed-off laser tubes has been demonstrated with no apparent lifetime limitations. Several new pump lamp designs have been developed and tested to overcome limitations set by emission line self-reversal, cataphoresis,

Proceedings of the IEEE, 1966
After a general discussion of the merits of glass vs. crystals as host materials for laser ions, a summary is given of the various glass lasers. Because of its importance as an efficient, room temperature laser the properties of neodymium are considered in greater detail.

Proceedings of the IEEE, 1966
This paper is a review of semiconductor laser work. The principles of operation are discussed. The stress is on work since early 1964. The present state-of-the-art in GaAs junction lasers is described.

Solar Energy Materials and Solar Cells, 2018
We demonstrate damage-free laser contact openings in silicon oxide layers on polycrystalline silicon on oxide (POLO) passivating contacts. A pulsed UV-laser evaporates the upper part of the polycrystalline silicon layer, lifting off the silicon oxide ...

Research on graphene abounds, from fundamental science to device applications. In pursuit of complementary morphologies, formation of graphene foams is often preferred over the native two-dimensional (2D) forms due to the higher available area.

Clinical Techniques in Small Animal Practice, 2004
The laser is a tool that will augment the surgical techniques available to the veterinarian. When using the laser compared with traditional surgery there are multiple procedures that can be performed with much greater ease, and some procedures that previously could not be performed.

Survey Review, 1974
Abstract Because lasers are being used increasingly in surveying, knowledge of the way in which a laser beam can damage the human eye is essential. This article describes the process by which damage to the retina may occur, and examines some methods by which this hazard can be reduced, if not eliminated.

Dispersion in a Laser Pumped Molecular Laser
1979 International Conference on Submillimeter Waves and Their Applications, 1979The dispersion equations have been derived for two laser fields of arbitrary intensity interacting with a homogeneously broadened, three-level molecular system. Good agreement is obtained between theoretical and experimental results for frequency detuning in a 385 μm, D 2 O laser and a 496 μm CH 3 F laser.

Diode Laser and Fractional Laser Innovations
Facial Plastic Surgery, 2019AbstractLaser technology continues to increase in popularity and expand treatment options for patients with common but challenging skin conditions including facial telangiectasias, facial aging, striae distensae, and acne scars. Facial telangiectasias have been estimated to occur in tens of millions of people worldwide.
