Rep. rate (kHz)

Controllable

Specified One rep. rate, such as 0.1Hz, 100 Hz, 500 Hz up to1kHz, with stable laser pulses emitting (stable pulse energy, peak, duration and period).

Different rep. rate in the range of 0.1Hz to1kHz can be obtained by input an external TTL signal.

Uncontrollable

Undefined rep. rate among 2kHz-3kHz and unstable laser pulse emitting. Suitable for the applications only needing high peak power pulses.

Average power (mW)

Average power (mW) = Single pulse energy (µJ) * Rep. rate (kHz)
