Photoacoustic Imaging Sources BENEFITS High pulse energy (up to 230 mJ) is highly beneficial for photoacoustics imaging applications Superior tuning resolution (1 – 2 cm⁻¹) allows recording of high quality spectra High integration level saves space in the laboratory Flashlamps replacement without misalignment of the laser cavity saves on maintenance costs In-house design and manufacturing of complete systems, including pump lasers, guarantees on-time warranty and post warranty services and spares supply Variety of control interfaces: USB, RS232, optional LAN and WLAN ensures easy control and integration with other equipment Attenuator and fiber bundle coupling options facilitate incorporation of PhotoSonus T systems into various experimental environments Savanoriu Av. 237, LT-02300 Vilnius, Lithuania | Ph. +370 5 2649629 | e-mail: [email protected] | www.ekspla.com

High Energy Table-Top Tunable Wavelength Lasers for Photoacoustic Imaging PhotoSonus T series tunable laser seamlessly integrates in a compact housing a nanosecond optical parametric oscillator and Nd:YAG Q-switched laser. Three models with different output pulse energy values and different repetition rates are offered. The most powerful model has more than 230 mJ pulse energy. Narrow linewidth (<10 cm⁻¹) is nearly constant trough almost whole tuning range, which makes laser suitable for many spectroscopy application. The device is controlled from the remote keypad or PC using LabVIEW™ drivers...

Typical far field beam profile of PhotoSonus T laser at 800 nm Ordering information Note: Laser must be connected to the mains electricity all the time. If there will be no mains electricity for longer that 1 hour then laser (system) needs warm up for a few hours before switching on. energy version (10 Hz only) Repetition rate: range (for T+ model only) FBC fiber or fiber bundle coupling of OPO output without attenuator Water-air...
