Technical ñharacteristics

Lasers of the DPL series are both high efficient and reliable Nd:YAG - diode pumped Q-switched acoustic optical lasers. In the DPL series the widely known optical scheme with the transverse pump of the active medium rod is employed incorporating laser diode arrays. The laser head is compact extremely rugged and shock-proof, allowing maintenance-free operation. The case of the laser head is hermetically sealed. The laser is supplied by the system of the power control and pilot laser.
Unique laser device provides the ideal system which takes the advantage of the output parameters in various applications such as precise technology, ablation, etc.
