Publikováno v: Optical Engineering. 59:1

An experimental setup with a laser fiber optic probe has been developed, and the vibration dynamics of the vocal folds (VFs) in the larynx of rabbits have been studied. VF vibrations were excited by a variable pressure air stream. We found that, at a

Stabilisation of a radiation wavelength of a nanosecond fibre laser by a passive nonlinear loop mirror

Autor: M I Belovolov, Oleg I. Medvedkov, Mikhail M. Bubnov, Mikhail E. Likhachev, Svetlana S. Aleshkina

Publikováno v: Quantum Electronics. 46:1089-1091

A method for stabilising the radiation wavelength of a mode-locked fibre nanosecond laser is proposed and realised. Generation of nanosecond laser pulses with a spectral bandwidth of , which corresponds to a transform-limited pulse, is demonstrated.

Tunable Bismuth-Doped Fiber Laser for a Spectral Region of 1360-1510 nm

Autor: M I Belovolov, Sergei V. Firstov, Vladimir F. Khopin, Evgeny M. Dianov, Vladimir M Paramonov, Mikhail Melkumov, A N Gur'yanov

Publikováno v: Lasers Congress 2016 (ASSL, LSC, LAC).

A Bismuth-doped fiber laser tunable in the new wavelength range 1360-1510 nm with the output power 50 mW has been developed for the first time. The tuning of the laser was carried out by rotating diffraction grating.

Pulsed generation in a combined-diode-pumped Nd3+:Ca3Ga2Ge3O12laser with a small jitter of the pulse repetition rate

Autor: M I Belovolov, A F Shatalov

Publikováno v: Quantum Electronics. 39:25-30

Pulsed generation in a solid-state Nd3+:Ca3Ga2Ge3O12 (Nd:CGGG) laser (SSL) with passive Q-switching by the Cr4+:YAG crystal is studied. To reduce the pulse repetition rate jitter of the SSL generation, the current through a pump diode was combined fr
