The TOPOL is a synchronously pumped femtosecond optical parametric oscillator (OPO). The system is pumped by a mode-locked femtosecond laser with central wavelength of 1030-1060 nm and about 70 MHz pulse repetition rate. The pumping is done either at fundamental or SH wavelength (depending on the OPO model). The SHG module for the pump laser (where required) is built into the TOPOL's layout. Thus, all models are optimized for external pumping by the TEMA-150 laser system's fundamental frequency. However, the OPO may be adapted to other pump laser specifications upon request.

The system is housed in a single compact body and has two main outputs for signal and idler wavelengths. Exact tuning ranges vary from model to model. The unit features a built-in power meter and a spectrometer unit for robust monitoring of the unit's output. Optional outputs are available for pump radiation and its SH. The unit is fully controlled via Windows PC with USB interface, Windows software is supplied in the package.

TeMa-150 femtosecond pump laser;
- auxiliary 1050-nm pump laser output;
- auxiliary 525-nm pump SH output (in certain models);
- adaptation to other pump laser parameters (PRR 50...100 MHz).
