Single pulse energy
Pulse duration
Average power (mW)
Average power (mW) = Single pulse energy (uJ) * 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.
