Latest Patents

Antanavičius holds a patent for a "Wavelength-tunable source of pulsed laser radiation for VIS-NIR spectroscopy." This invention consists of a pump source that forms bursts of picosecond pulses at a high pulse repetition rate. The system includes a synchronously pumped optical parametric oscillator, which is crucial for achieving the desired wavelength tunability. The pump source features a solid-state regenerative amplifier with electro-optical switches that create partial transmission within the resonator. This design allows for the ejection of energy from circulating pulses, resulting in bursts of 5-10 ns duration filled with high peak power picosecond pulses. The pulse repetition rate can reach GHz levels, enabling the construction of a compact optical parametric oscillator. The parameters of this invention ensure high energy efficiency, stability, and the ability to provide output pulse bursts at up to 10 kHz repetition rate.
