…compartment includes two built-in modules that are key to achieving superior materials processing outcomes. A built-in attenuator allows software control of the pulse energy without compromising the beam mode quality; a software controlled acousto-optic modulator acts as a high speed process…

Pulse Switch for Mira 900

Pulse Switch for Mira 900

…HERE Cavity Dumper Accessory With Pulse Switch, the Mira cavity is extended to include the Pulse Switch’s acousto-optic modulator. By using intracavity acousto-optic modulation to switch pulses out of the Mira cavity, Pulse Switch provides a convenient way both to reduce laser repetition rate and…

…In order to circumvent this condition, an external modulator can provide a very effective way to modulate the laser beam down to very low duty cycles. Acoustooptics modulators are most commonly used for this task, but electro-optic modulators can also be employed. These devices can either totally…
