B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus offers consumers dye lasers with distributed feedback of spectrum tunable subnanosecond and picosecond radiation pulses «WIPER TOPAZ-PS» under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus manufactures dye lasers with distributed feedback (DFB) «WIPER TOPAZ-PS» is designed to produce narrow-band spectrum tunable radiation of subnanosecond and picosecond duration when excited by radiation of the 2nd and 3rd harmonics of subnanosecond solidstate diode-pumped Nd:YAG-, Nd:LSB- and Nd:YLF-microlasers.

Difference of the DFB laser from traditional dye lasers with the same spectral characteristics consists in:
* absence of the external resonator and spectral-selective elements;
* significantly high efficiency of pumping radiation conversion into a narrow dye generation line;
* wider adjustment range without exciting the background of enhanced spontaneous radiation;
* ability of direct obtaining of spectral-limited single picosecond pulses at nano- / subnanosecond excitation;
* ability to work in frequency mode with no pumping of active medium through the cuvette;
* simple construction, reliability and easy to use.
