NT352 series tunable laser seamlessly integrates in a compact housing a nanosecond optical parametric oscillator and Nd:YAG Q-switched laser.
Three models with different output pulse energy values are offered. The most powerful model has more than 150 mJ pulse energy at 700 nm. Narrow linewidth (<10 cm⁻¹) is nearly constant trough whole tuning range, which makes laser suitable for many spectroscopy application.
The device is controlled from the remote keypad or from PC through RS232 interface using LabVIEW™ drivers that are supplied with the system. The remote pad features a backlit display that is easy to read even while wearing laser safety glasses.
System is designed for easy and cost-effective maintenance. Replacement of flashlamps can be done without misalignment of the laser cavity and deterioration of laser performance. OPO pump energy monitoring system helps to increase lifetime of the optical components.
Optional items are available allowing optimization of the laser system for Your application, for example:
