Title: Saturable absorber for fiber laser mode- locking,fiber bragg grating with a saturable absorption property and mode-locked fiber laser.
Inventor: RUSTEIKA NERIJUS
IPC: G02B6/00
Filed: 2012-07-25
Abstract: The present invention relates to lasers, more particularly, it relates to saturable absorbers, and is suitable for fiber laser mode-locking. This invention can be employed for generation of ultrashort light pulses which have applications in various areas such as scientific research, material processing, medicine and other. A saturable absorber for fiber laser mode-locking comprises a single-mode optical fiber having a fiber portion which is tapered or in which at least one longitudinal groove or at least one transverse hole is formed. Said tapered fiber portion is coated with a composite bleachable material, or said grooves or holes are filled with said composite material. In order to broaden a range of applications of the saturable and to extend its service life, said composite bleachable material comprises an inorganic matrix with an index of refraction similar to an index of refraction of the optical fiber and a nonlinear material embedded into said inorganic matrix, wherein said nonlinear material possesses a nonlinear absorption property and bleaches when exposed to laser radiation of intensity from 5MW/cm2 to 500MW/cm2, while a waist diameter and of said tapered fiber portion or a number of grooves or holes and their configuration are chosen to satisfy a condition that laser light while propagating in the saturable absorber experiences losses between 1% and 50%. The proposed saturable absorber can be used in a resonator of a mode-locked fiber laser or incorporated into a construction of a fiber Bragg grating.

Title: Method for manufacturing of spatially variant waveplates
Inventor: ULČINAS ORESTAS
IPC: B44C1/00
Filed: 2018-06-22
Abstract: The invention relates to volume modification of transparent materials by means of ultrashort laser pulses. A method of forming highly transparent spatially variant waveplates includes focussing Gaussian laser beam with pulse duration 500 fs to 2000 fs inside of material transparent to laser wavelength building self-organizing structures of nanoplates. The workpiece is moved in three coordinates relatively to beam focus along desired line. A combination of focus area, pulse repetition rate, energy and velocity of movement is selected to locate said structures inside of the workpiece for acting as birefringent optical elements with specific retardance. Energy of pulses exceeds the threshold of building nanoplates in part of the focal area limited by -o/2 and o/2 where o is standard deviation from maximum of Gaussian function. The energy of pulses creating nanoplates is accumulated in said area from the sequence of 1000 to 2000 pulses in total not exceeding 0,2-0,3 µJ.

Title: Method and arrangement for operating with different data speeds in digital data communication network
Inventor: HERSCHTAL L
IPC: H04J3/00
Filed: 1978-08-23
Abstract: The present invention concerns a method and arrangement to enable connections in a data communication network between terminal layouts, such as telephone sets A, B, in figure 1, even in such cases where said terminal devices A, B are configured to work with different data speeds or when the connection between these terminal devices in the data communication network includes transfer devices, such as data links, that work with a data speed different from the data speed used by the terminal devices. This is achieved in that the particular digital terminal device A, B is configured to extract clock signals from digital data received from the data communication network to generate a local clock signal to set the time for the data bit rate from the terminal device and respond either to a digital code word that is received or to the bit rate of incoming data so as to send data with different bit rate at respective times, and for this purpose it is outfitted with a period measuring circuit 40, figure 2, for determining the data rate of the incoming signals, and a time circuit 41 which can be actuated by the period measuring circuit for switching between two different conditions which are related to different data speeds, so that a clock extraction circuit 2 in the time circuit 41 is made to extract the clock signal from the separate incoming data. <IMAGE>
