A diode pumped q-switched Nd:YVO4 laser offers up to 6 W output power and high 40 kHz repetition rate. End-pumped design ensures compact size of the laser cavity. Down to 6 ns pulse duration is achieved due to the innovative q-switching. Short pulse duration, high repetition rate and comact design make this laser an attractive tool for wide range of material processing applications.
Featuring compact size and turn-key operation NL640 series laser is ideal for integrating into micromachining or marking systems with limited space availability and tough weight requirements. Sealed cavity as well as rugged body ensures reliable 24/7 operation.
