…small size of the NPRO and pump
diodes results in a small head size, making it
straightforward to precisely stabilize the operating
temperature.
Summary
Mephisto lasers fully exploit the unique potential of the
NPRO laser architecture. Their excellent laser beam

update
CO laser is less than 25µm. On the other
hand, achieving the same spot size with
both wavelengths can be accomplished
with smaller optics at the shorter wavelength. This in turn allows for smaller/
faster…

…The laser is the cutting tool of choice in many heavy metal applications because of its unique combination of advantages that stem from its small spot size and high power density. These advantages include a small heat-affected zone (HAZ), virtually no part distortion, high quality on both cut edges,…

…thick fused silica AR coated entrance window. The Gaussian beam waist at
the focus was measured to be ~160 µm, satisfying the condition w0
= 0.64a for optimal energy
coupling into a hollow core fiber and resulting in focal spot intensities on the order of 1014
W/cm2. The exact…

range of 500 W to 10 kW, and can readily
achieve focused spot sizes in the necessary range between 40 and 800 µm, even
at relatively large working distances.
From a practical standpoint, the use of
beam delivery fiber expands integration
options and facilitates the…

…from 10 kHz to 30 kHz. A beam parameter product of typical 20 mm x mrad (for a 400 m, round core output fiber) enables this power to be effectively concentrated into small focused spot sizes. The unique combination high average power, high pulse energy and superior beam quality makes the HighLight…

…material,
meaning there is little peripheral damage. Plus, shorter
wavelength, deep-ultraviolet light can be focused to a given
spot size with a greater depth of focus than longer
wavelengths. Most important of all, these high energy UV
photons vaporize target material in…

…steel and titanium In coloured marking on metals, such as steel and titanium, the output of a Coherent picosecond laser is focused down to a small spot size on the workpiece. The highly localised energy delivered by the laser oxidises the metal atoms at the surface of the material and forms a metal…

…factors which determine the type of beam profiler to use are beam size, laser power and
operating mode (CW or pulsed). Knife-edge scanners are most useful with very small beams, CW
lasers and high power lasers. Camera-based systems work with larger beams, and either pulsed or
CW…

…miniaturized, the cavity has been designed to deliver a
circular beam with excellent mode quality by carefully
matching the crystal size to the cavity dimensions, and
thus the mode volume of the intracavity beam.
Typically, these lasers deliver M2 < 1.25, making them
