Nanosecond laser system NL230

LIDARindustrialTi:sapphire

The NL230 series diode-pumped short nanosecond lasers are designed to produce high-intensity, high-brightness pulses and are targeted for applications such as material ablation, Light Detection And Ranging (LIDAR), remote sensing, mass spectroscopy, OPO, Ti:Sapphire or dye laser pumping and many more. Diode pumping allows maintenance-free laser operation for an extended period of time – more than 3 years for an estimated eight working hours per day.

Description
The NL230 series lasers are built with robust, sealed, and precisely machined monolithic aluminium blocks, ensuring reliable operation in harsh industrial environments, such as laser-induced breakdown spectroscopy (LIBS). Second and third harmonic options expand the range of applications, where high pulse energy and high pulse-to-pulse stability are required. For easy and seamless control and integration with other industrial equipment, the NL230 series laser is equipped with USB/RS232 interfaces and can be externally triggered with a jitter as low as < 0.5 ns StDev. NL230 series lasers are designed to work reliably 24/7 in an industrial environment.

Benefits

• Short duration 3–6 ns pulses ensure strong interaction with material, highly suitable for LIBS
• User selectable wavelength single axis output is superior for experiments requiring alternating wavelengths, such as material ablation and LIBS
• Rugged, monolithic design enables laser usage in harsh environments
• Diode pumped design provides quiet operation, eliminates the irritation of flash light
• Variety of interfaces (USB, RS232, LAN, WLAN) ensures easy control and integration with other equipment
