Rep. rate (kHz)

Controllable

Fixed rep. rate, such as 1k, 2k, 3k, 4kHz, with stable laser pulses emitting (stable pulse energy, peak, duration and period).

Different rep. rate in the range of 1kHz-4kHz can be obtained by input an external TTL signal.

Uncontrollable

Undefined rep. rate among 5k-7kHz 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)

Remarks

Please Note: because of the Walk-off effect of Nonlinear crystals, the beam quality of UV laser is not so good as that of 1064/532nm laser.
