The YLPN-1-1x350-XX series nanosecond fiber lasers deliver up to 50 W of average power, operating in pulsed mode with selectable pulse durations of 1.5 to 300 ns. With modulation frequencies ranging from 1.6 kHz to 4 MHz, they offer broad flexibility for high-precision applications. Laser output is delivered through an optical fiber (up to 2 meters), with an integrated optical isolator in the collimator to protect against back reflections. Highly versatile and reliable, these lasers are ideal for a wide range of marking and engraving tasks across various materials.
