Title: Mikhail Abramov: Innovator in Fiber Laser Technology

Introduction

Mikhail Abramov is a prominent inventor based in Burbach, Germany. He has made significant contributions to the field of fiber laser technology, holding a total of three patents. His work focuses on enhancing the performance and efficiency of high-power fiber laser systems.

Latest Patents

One of Mikhail Abramov's latest patents is an ultra-high power single mode fiber laser system with a non-uniformly configured fiber-to-fiber rod multimode amplifier. This innovative system includes a booster winch configured as a fiber amplifier that extends over free space. It features a pump source and a laser head with a reflective element that receives pump light and reflects it toward the output end of the booster in a counter signal-propagating direction. The design of the booster incorporates concentric and coextending frustoconically shaped core and cladding, which effectively suppresses the amplification of high order modes while allowing single mode signal light to propagate efficiently.

Another notable patent is the high power metal clad mode absorber. This unit is designed to be placed on a passive fiber of a high power fiber laser system, effectively trapping and removing high order modes that propagate along the clad of the passive fiber. The mode absorber is composed of one or more liquid metals and alloys, strategically placed in an opening formed in the sheath of the passive fiber. This composition is engineered to remove multimode light with a predetermined power level, heating the material at a temperature lower than the threshold at which the absorber may be damaged.
