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 valuable 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

Description & Options

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 that are supplied with the system. The remote pad features a backlit display that is easy to read even while wearing laser safety glasses.

System is designed for easy and cost-effective maintenance. Replacement of flashlamps can be done without misalignment of the laser cavity and deterioration of laser performance. OPO pump energy monitoring system helps to increase lifetime of the optical components.

OPTIONS

Optional items are available allowing optimization of the laser system for Your application, for example:

Fiber bundle coupled output;
Energy meter;
Efficient second harmonic generator for 330 – 660 nm range;
Pulse energy attenuator;
Water-air cooled power supply.

Please inquire custom-build versions and options.

Due to continuous improvement, all specifications are subject to change without notice. The parameters marked typical are not specifications. They are indications of typical performance and will vary with each unit we manufacture. Unless stated otherwise all specifications are measured at 700 nm and for basic system without options.
Optional signal extended range: 660 – 1320 nm.
When extended signal range is selected.
See tuning curves for typical outputs at different wavelengths.
At 700 nm or higher wavelengths.
When wavelength is controlled from PC. When wavelength is controlled from keypad, tuning resolution is 0.1 nm for signal, 1 nm for idler and 0.5 nm for SH.
FWHM measured with photodiode featuring 1 ns rise time and 300 MHz bandwidth oscilloscope.
Beam diameter is measured at 700 nm at the 1/e² level and can vary depending on the pump pulse energy.
Full angle measured at the FWHM level at 700 nm.
Separate output port for the 532 nm beam is standard. Output for 1064 nm beam is optional. Pump laser output will be optimized for the best OPO operation and specification may vary with each unit we manufacture.
Air cooled power supply is available as option.
Mains voltage should be specified when ordering.

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.
