Higher imaging depth and resolution in photoacoustics will be available with a new laser source from Ekspla

07.04.2020 - 13:22

Ekspla introduced a new high-energy laser source version for photoacoustic imaging applications. For researchers requesting higher sample imaging depth and resolution, PhotoSonus+ delivers up to 250 mJ of pulse energy at 10 Hz repetition rate.

PhotoSonus+ photoaoustic imaging laser source consists of a high energy Q-switched laser, parametric oscillator, power supply, and cooling unit, all integrated in a single robust cart-type housing to provide mobility, ease of use and low maintenance costs.

The highly flexible PhotoSonus platform makes it easily integrated and used in a photoacoustic imaging system. It is fully motorized and computer-controlled, with user trigger outputs and inputs and special options such as motorized switching between OPO Signal and Idler, motorized attenuator, internal energy meter, and electromechanical output shutter.

Fast wavelength switching option enables each laser pulse to have at different wavelengths within the entire signal or idler range, at any step, and in any order. This new feature, combining high pulse energy (up to 250 mJ) and wide wavelength tuning range (660 – 2300 nm) makes PhotoSonus an irreplaceable imaging source for any photoacoustic system.

For user convenience, the output of PhotoSonus+ laser can be customized for being coupled with any type of fiber bundle.

Now, with the new model introduced, the PhotoSonus laser family features three product lines dedicated to specific photoacoustic imaging applications. The DPSS laser-based photoacoustic source PhotoSonus X is targeted for customers where a high data acquisition rate is preferable as it provides up to 50 mJ at 100 Hz or up to 65 mJ at 50 Hz. PhotoSonus represents the classic „all-rounder approach“ and delivers up to 160 mJ at 20 Hz or up to 180 mJ at 10 Hz. While Photosonus+ is built for researchers wishing to probe even deeper into tissues.
