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

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 options such as motorized switching between OPO and pump wavelengths.

Parametric oscillator generates output energies up to 180 mJ at peak of wide wavelength tuning range (660 – 2300 nm). Customizable and interlocked fiber bundle connector ensures safety and ability to fit various size fiber bundles.

For customers who demand even higher output energy, we are introducing PhotoSonus with High Energy option. 250 mJ output energy is achieved at the peak from OPO at 10 Hz. For more details inquire separately.
