The NT340 Series from EKSPLA are Tunable Wavelength Nanosecond Lasers that operate from 192 to 4400 nm. The devices deliver high pulse energy of up to 50 mJ in visible spectral range, up to 10 mJ pulse energy in UV spectral range, and up to 15 mJ pulse energy in MIR spectral range. They have a pulse duration of 3 to 5 ns and a pulse repetition rate of up to 20 Hz. Their narrow linewidth (down to 3 cm-¹) and superior tuning resolution (1 - 2 cm-¹) allows for recording of high-quality spectra.
The NT340 Series high-energy lasers integrate the nanosecond optical parametric oscillator and the Q-switched nanosecond laser &ndash all in a compact housing. They feature hands-free wavelength tuning from UV to IR, high conversion efficiency, optional fiber-coupled output, and separate output port for pump laser beam. The oscillator cavity of these lasers is hermetically sealed which protects non-linear crystals from dust and humidity.
The NT340 Series can be controlled from remote keypad or PC using LabView drivers that are supplied with the system. They also feature an OPO pump energy monitoring system that helps to control pump laser parameters. These lasers are available in a benchtop package that measures 456 × 821× 270 mm with a variety of control interfaces: USB, RS232, LAN, and WLAN that ensures easy control and integration with other equipment. They come with attenuator and fiber coupling options to facilitate the incorporation of NT340 systems into various experimental environments. The lasers are available with a separate shared output port for 532/1064 nm beam (separate output port for the 355 nm beam is standard). They are ideal for use in laser-induced fluorescence, flash photolysis, photobiology, remote sensing, time-resolved spectroscopy, non-linear spectroscopy applications.
