the tubular sheath (3) of the head (1) has two windows, working upstream and downstream (4), (5), each of which is mounted with respect to a reference mirror, a mirror (12), respectively, and a partially reflecting mirror (14) for totally reflecting.a first optical device (8) is ...
LASER WELDING HEAD FOR SLEEVE-TO-TUBE WELDING 38\nABSTRACT OF THE DISCLOSURE\nThe invention relates to a laser welding head for\nwelding a sleeve within a tube by fusing the interface\nbetween the sleeve and tube with a laser beam. The laser\nwelding head has a cylindrical housing ... ...
For monitoring the working of a workpiece (W) with pulsed radiation of an excimer laser the workpiece surface is periodically illuminated with visible light (B) synchronously with at least some of the laser pulses. A mirror arrangement (S) separates visible light from ultraviolet laser light so ...

Working of DFB Laser A distributed-feedback laser is a laser in which the whole resonator is made up of a pattern in thelaser host materialthat functions as a distributed Bragg reflector throughout the range of wavelengths of laser activity. The device features various axial resonator modes, al...
The laser working group considered several options to deliver synchronized laser pulses of the required energy to the photocathode and laser triggered switches. These requirements actually decreased during the course of the workshop, and the values finally settled upon (<10 {mu}J in 100 fs at {...
Working a workpiece (1) using a laser beam (2) comprises moving the workpiece with respect to the beam, or vice-versa, to produce a melt (3). Current is applied to the melt to produce a field with divergent or convergent lines of current, without applying an external magnetic field.收藏...
