Average power
Average power (mW) = Single pulse energy (μJ) * Rep. rate (kHz)
Rep. rate (kHz)
Specified One rep. rate, such as 1k, 2k, 3k, up to 4kHz, with stable laser pulses emitting (stable pulse energy, peak, duration and period).
Different rep. rate in the range of 1Hz-4kHz can be obtained by input an external TTL signal.
Undefined rep. rate among 5k-20kHz and unstable laser pulse emitting. Suitable for the applications only needing high peak power pulses.

See the Glossary and Technology for information about the terms used
In the front of the laser, we add an infrared filter. The residual IR part is less than 10-3. Please refer to the technology page for more information about the filter.
Other Sytles and custom designs are available. Contact us to discuss your needs.
