NT340C series tunable optical parametric oscillator (OPO) laser systems from Ekspla offer hands-free, no-gap ultraviolet tuning from 210 to 2300 nm.Offering excellent beam shape (1.5:1 ellipticity), the NT340C series laser establishes itself as a versatile tool for many laboratories. Excellent ultraviolet (UV) conversion efficiency ensures up to 5 mJ energy in UV and makes NT340/UVE systems an excellent choice for a wide range of applications including: spectroscopy, photobiology, laser-induced fluorescence, photolysis, remote sensing, LIDAR and many others.Virtually zero warm-up time (a few seconds) and OPO pump-energy monitoring ensure customer-friendly and reliable operation of the whole system. NT340C series systems are controlled from a computer using supplied LabView drivers or the user-friendly remote control pad. The system provides simple operation and monitoring of output parameters and convenient integration into measurement setups.The whole system comprises a nanosecond Q-switched Nd:YAG pump laser and OPO in a single compact housing. As a standard feature, the system has a separate output for the 355-nm pump beam. Outputs for 1064, 532 and 266 nm are available on request as well as other customized options.
