Even more research possibilities by employing new high-energy tunable wavelength lasers

07 May 2020

Ekspla updated it‘s range of high-energy tunable wavelength lasers. Various options and model upgrades will make these tunable nanosecond lasers even more versatile and able to be tailored for specific applications and/or requirements. The main upgrades were implemented into the two main series of high-energy tunable lasers – NT340 and NT350.

Two main upgrades were introduced, extending the flagship model NT340 tuning range. The MIR option helps researchers to step into mid-infrared territory by providing a tuning range from 2500 to 4400 nm. By employing customized options (available on separate request), the tuning range of the NT340 can be extended to 18 000 nm for specific applications like studies of IR vibrations of molecules.

The biggest news among NT350 series tunable lasers is the newly introduced model – NT352E. High energy, up to 250 mJ pulses are delivered and are highly beneficial for photoacoustics imaging applications. By employing an SH extension, the gap free tuning range of all models can be extended to 330-2600 nm. For more control over experiments and  protection of valuable optics, an optional energy meter can be installed.

The recently announced fast wavelength switching (FWS) option will be available for the NT350 series laser. Users employing lasers with this option installed will be able to preprogram almost any number of desired wavelengths (within the tuning range) to be emitted at almost any step and in any order. For applications like photoacoustic imaging, where initiation of acoustic response of materials using light within a short time period is needed, this function should be especially attractive.

NT340 or NT350 series tunable lasers seamlessly integrate, in a compact housing, a nanosecond optical parametric oscillator and Nd:YAG Q-switched laser. The high integration level saves valuable space in the laboratory.

For researchers working in applications where ultimate precision is essential , the lasers ensure superior tuning resolution (1 – 2 cm⁻¹) which allows recording of high quality spectra.

The 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. The OPO pump energy monitoring system helps to increase the lifetime of the optical components.

The device is controlled from the remote keypad or PC using LabVIEW™ drivers that are supplied with the system. Employing a variety of control interfaces: USB, RS232, LAN and WLAN ensures easy control and integration with other equipment (optional).

Rearranged set of attenuator models and fiber bundle coupling options facilitate incorporation of NT340 and NT350 systems into various experimental environments.
