BeamMaster USB Knife-Edge Based Beam Profilers

BeamMaster USB Knife-Edge Based Beam Profilers

…from 800-1800 nm (InGaAs). Input powers can be as low as 10 µW. There is automatic gain control and an internal distortion-free optical attenuation filter provided (Si models). Beam Profiles and Widths On each rotation of the drum, BeamMaster captures and processes the data from the passage of the…

…spacing larger than the gain bandwidth, and only one mode
lases. Generally, though, a filtering element that preferentially passes only one mode is inserted into the cavity. The most common type of filter is called an
etalon. Using a number of sophisticated design enhancements, it is…

…typical flow diagram is shown in Figure 1. The delivery system
and/or laser power detector may be connected in parallel auxiliary
loops as long as they do not reduce the required flow to the laser, or
they may be cooled by a separate chiller.
If using the optional liquid-cooled…

…in order to keep
the free electrons, released by a heater close to the cathode.
By applying a positive trigger pulse, the electrons can pass
the grid and the thyratron switches to the conductive mode.
Improved thyratron designs with additional grids helped to
achieve a…

have that window removed and include
a laser-grade, low-distortion filter with
each camera instead. This camera hardware is then calibrated for linearity and
tested to ensure it is accurately measuring beam…
