Single-shot femtosecond bulk micromachining of silicon with mid-IR tightly focused beams

Autor: Evgenii Mareev, Andrey Pushkin, Ekaterina Migal, Kirill Lvov, Sergey Stremoukhov, Fedor Potemkin

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-12 (2022)

Abstract Being the second most abundant element on earth after oxygen, silicon remains the working horse for key technologies for the years. Novel photonics platform for high-speed data transfer and optical memory demands higher flexibility of the si

Refining the Performance of mid-IR CPA Laser Systems Based on Fe-Doped Chalcogenides for Nonlinear Photonics

Autor: Andrey Pushkin, Fedor Potemkin

Publikováno v: Photonics, Vol 10, Iss 12, p 1375 (2023)

The chirped pulse amplification (CPA) systems based on transition-metal-ion-doped chalcogenide crystals are promising powerful ultrafast laser sources providing access to sub-TW laser pulses in the mid-IR region, which are highly relevant for essenti

High-Power Solid-State Near- and Mid-IR Ultrafast Laser Sources for Strong-Field Science

Autor: Andrey Pushkin, Ekaterina Migal, Dina Suleimanova, Evgeniy Mareev, Fedor Potemkin

Publikováno v: Photonics, Vol 9, Iss 2, p 90 (2022)

This review highlights the development of ultrafast sources in the near- and middle-IR range, developed in the laboratory of Nonlinear Optics and Superstrong Laser Fields at Lomonosov Moscow State University. The design of laser systems is based on a

Control of spectral shift, broadening, and pulse compression during mid-IR self-guiding in high-pressure gases and their mixtures

Autor: Ekaterina Migal, Andrey Pushkin, Nikita Minaev, Boris Bravy, Fedor Potemkin

Publikováno v: Optics letters. 47(4)

Precise control of the nonlinear optical phenomena is the limiting factor for the spectral broadening and pulse compression techniques for high-power laser systems. Here we demonstrate that generation of the blue and red components under filamentatio

High-gain broadband laser amplification of mid-IR pulses in Fe:CdSe crystal at 5 μm with millijoule output energy and multigigawatt peak power

Autor: Andrey Pushkin, Fedor Potemkin

Publikováno v: Optics Letters. 47:5762

We report on a first of its kind, to our knowledge broadband amplification in a Fe:CdSe single crystal in the mid-IR beyond 5 µm. The experimentally measured gain properties demonstrate saturation fluence close to 13 mJ/cm2 and support the bandwidth
