Ekspla's  NT230 series lasers deliver high up to 10 mJ energy pulses at 100 Hz pulse repetition rate, tunable over a broad spectral range. Integrated into a single compact housing, the diode pumped Q-switched Nd:YAG laser and Optical Paramteric Oscillator (OPO) offers hands‑free, no-gap tuning from 192 to 2600 nm. With its 100 Hz repetition rate, the NT230 series laser establishes itself as a versatile tool for many laboratory applications, as laser induced fluorescence, flash photolysis, photobiology, metrology, remote sensing, etc.

Due to the innovative diode‑pumped design, NT230 series lasers features maintenance-free laser operation for an extended period of time and improved stability (compared with flash-lamp pumped counterparts).

NT230 series systems can be controlled from a user-friendly remote control pad or/and a computer using supplied LabVIEW™ drivers. The control pad allows easy control of all parameters and features on a backlit system display that is easy to read even with laser safety eyewear.

Due to DPSS pump source, the laser requires little maintenance. It is cooled by a built-in chiller, which further reduces running costs. An OPO pump energy monitor allows monitoring of pump laser performance. A standard feature includes a separate output port for the 355 nm pump beam. Read more.

Following the demand of high output energies in the photoacoustic market for imaging larger volumes of tissue, the Ekspla PhotoSonus, a new high energy tunable laser source for photo-acoustic imaging has been introduced. Time-tested Ekspla nanosecond pump laser, parametric oscillator, power supply and cooling unit are integrated in a single robust housing to provide mobility and ease of use.

Highly flexible PhotoSonus platform makes it easy to be integrated and used in a photoacoustic imaging system: it is fully motorized and computer controlled, have user trigger outputs/inputs and special functions as fast tuning between OPO wavelengths. Parametric oscillator generates output energies up to 200 mJ at peak. Achieving a highly uniform spatial distribution from OPO and adjustable beam diameter helps homogeneously couple various size fiber bundles and deliver balanced energy light to the target. By employing a wide range of other options (like access to OPO idler range, toggling between OPO and fundamental wavelengths through simultaneous output), this laser system can be modified to specific user requirements in order to expand photo-acoustic imaging possibilities.
