Latest Patents

Dmitry's latest patents include the "Pulse Configurable Fiber Laser Unit" and the "Chirped Pulse Amplification Laser System." The Pulse Configurable Fiber Laser Unit is an environmentally stable, mechanically robust, and maintenance-free ultrafast laser source. It features a reliable, self-starting fiber oscillator and an integrated programmable pulse shaper. This combination allows for the generation of broad bandwidth ultrashort pulse durations and arbitrary waveform generation through spectral phase manipulation. The laser can routinely deliver near-transform limited, sub-60 fs pulses with megawatt-level peak power. Additionally, the output pulse dispersion can be tuned to pre-compensate for phase distortions and optimize the pulse profile for specific applications.

The Chirped Pulse Amplification Laser System focuses on outputting nearly transform limited pulses by utilizing a mode-locked laser. This system temporarily stretches the TL pulses using a first Bragg grating, which imparts a chirp that is compensated for by a second Bragg grating acting as a compressor. The system includes a pulse shaping unit that measures the spectral phase across the recompressed pulse and adjusts the deviation from that of the TL pulse by generating a corrective signal. This corrective signal is applied to actuators coupled to segments of one of the Bragg gratings, allowing for desired phase changes.
