✦ Synopsis

According to UN publications landmines are a daily
threat in approximately 70 countries of the world. There exist
different ways to destroy detected antipersonnel mines.
Neutralisation of mines with laser is a possibility that offers
several advantages like working from safe distance and possibly
mine destruction by deflagration and without explosion. Previous
work has shown the importance of an absorbing mine wrapping
material to achieve the desired burning process. In this paper,
interaction of Nd:YAG laser radiation with different realistic
synthetic mine wrapping materials is investigated. Penetration
duration of laser radiation at λ = 1.064 μm through
samples with different thickness is measured. Penetration through
all tested materials is achieved at an incident power of 28.8 W.
With an investigated material thickness up to 3 mm, penetration
duration is in the range of seconds. Also penetration through a
real mine case consisting of bakelite is achieved.

This paper describes the stabilization and guidance of plasma plumes through the interaction with low power laser radiation. The stabilization and guidance have been found to be governed by several physical effects. One effect is the localized rise of electrical conductivity. As the laser provides a

Titanium materials exhibit a property profile that is just as versatile as that of steel materials. Titanium materials therefore have outstanding properties, such as excellent resistance to corrosion and high strength values at low densities, which makes them ideal for use in the chemical industry a

Eleven hepatic resections were performed by means of a divergent Nd:YAG laser. The beam was transmitted through a fiberoptic delivery system without any handpiece. The shortest resection time and most limited ischemic damage (4 mm) were obtained with 80-W power shoots and a low divergent beam (4'2 f
