PhotoSonus Series - Tunable Lasers for Photoaccoustic Imaging

The PhotoSonus series for photoacoustic imaging is dedicated for the analysis of larger volumes of tissue. There are two versions: PhotoSonus X is a low-maintainance tunable laser with integrated DPSS pump laser and OPO. It delivers up to 50 mJ at a repetition rate of 100 Hz in the wavelength tuning range from 660 to 2600 nm.

If a complete system combining pump laser, OPO, power supply and cooling system in single robust and mobile housing is preferred, then PhotoSonus+ is the right choice. Compared to PhotoSonus X, this system is available with up to >250 mJ @ 10 Hz.

Description 

Features

  • High pulse energy for larger area illumination
  • Fast wavelength tunability
  • Integrated pump laser, OPO and PSU in single portable unit or integrated pump laser and OPO with external power supply
  • Up to 250 mJ pulse energy
  • Low maintenance cost
  • Fiber bundle connectors with safety interlock

PhotoSonus and PhotoSonus+

Following the demand for 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, was 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. 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.

Recently, a fast wavelength switching option was introduced that enables each laser pulse to have a different wavelength within the entire signal or idler range and at any sequence. This new feature, combining high pulse energy (up to 180 mJ) and wide wavelength tuning range (660 – 2300 nm) makes PhotoSonus the irreplaceable imaging source for any photo acoustic system.

For even higher sample imaging depth and resolution a PhotoSonus+, with up to 250 mJ maximum pulse energy, was introduced.
For convenience, the outputs of PhotoSonus and PhotoSonus+ lasers can be coupled with almost any type of fiber bundle.

PhotoSonus X

PhotoSonus X is a perfect solution for photoacoustic imaging in pre-clinical and clinical use and when fast sample scanning is required. Having high output energy of up to 65 mJ at the peak, a broad wavelength tuning range from 665 to 2600 nm, high pulse repetition rate up to 100 Hz and fast wavelength switching makes it a perfect photoacoustic imaging source for gaining high-resolution images and ensuring high data acquisition rate. Moreover, being built on a diode pumped solid-state laser platform, PhotoSonus X assures significantly quieter operation (< 65 dB) compared with flash-lamp pumped lasers, which is very beneficial for clinical use.

Diode pumped laser technology and well-engineered system design ensures high reliability and low-cost system operation. PhotoSonus X output can be coupled with almost any type of fiber bundle.

With additional options of an internal energy meter and electromechanical shutter with laser self-test capability, PhotoSonus X can be ready for certification in clinical photoacoustic applications.
