Ekspla PhotoSonus: Mobile High Energy Tunable Laser System for Photoacoustic Imaging

PhotoSonus series High Energy tunable Lasers for PAT

  • High output energy for larger area illumination
  •  Pump laser, OPO and PSU in a single mobile unit
  •  Fast wavelength tuning available
  •  Turn-key operation and easy to use

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.

Features

  • High, up to 200 mJ, output energy
  • Fast wavelength tuning (10 Hz)
  • 10 Hz or 20 Hz pulse repetition rate
  • Integrated pump laser, OPO and PSU in single portable unit
  • Turn-key operation and easy to use
  • Customizable fiber output
  • Fully motorized wavelength tuning
  • Externally triggerable
  • PC control via USB port and LabVIEW drivers

Options

  • Rapid switching between OPO and pump wavelength (1064 nm)
  • Access to pump laser wavelengths (1064 / 532 nm)
  • Separate output of idler (1064 – 2300 nm)
  • Motorized attenuatorEnergy meter
