摘要： An ultra-long fiber-optic transmission system is configured in accordance with the current telecom standards and particularly advantageous for transmission data at a long distance which may exceed 400 km between adjacent nodes. The disclosed system has at least one intermediate amplifying node provided with a supervisory optical channel (SOC) which carries information between spaced nodes about the multi-wavelength optical signal as well as remote conditions at the optical terminal or regeneration site. The SOC comprises a transponder operative to select the direction in which an optical supervisory signal OSS, carrying information about the fiber break and malfunction of WDM channels, is transmitted along the SOC. The transponder further includes a receiver operative to measure the power of incoming OSS signal, which is indicative of the power of the transmitted and amplified WDM signal, and a Raman controller. The latter is coupled to the receiver and operative to either turn or turn off a pump of Raman amplifier based on determination of whether the measured power is lower than or at least equal to a reference value. The transponder is further configured with a transmitter configured as a fiber laser which operates in at least two modes. In the first mode when the measured power as at least equal to the reference value, the fiber laser emits the OSS having a nominal power. In the second mode, when the measured power is less than the reference value, the transmitter is operative to lase the OSS having a greater than nominal power even if Raman and EDFA amplifiers of the amplification node are disabled. The utilization of the fiber laser enhances the reliability and control of the long fiber-haul system's operation.

摘要： A method for contactless laser welding of a plurality of sheets of material stacked upon one another includes simultaneously delivering a laser beam and a stream of fluid through a laser head and further through an end cap which is removably mounted to the laser head. The end cap is configured with a stationary cylinder, which is coupled to the laser head, and a piston movable relative the cylinder. The piston moves in response to a pressure differential generated by the fluid in chambers above and below the piston. Once the pressure equilibrium is reached between the chambers, the pressure in the chamber below the piston is sufficient to reliably press the sheets of material against one another during a laser welding operation.

摘要： A WDM fiber optic communication system is operative to transmit WDM signals between multiple nodes. Each node has a booster EDFA, and in-band and out-of-band supervisory channels monitoring the integrity of a link by generating and detecting respective in-band and out-of-band control signals. The booster EDFA receives the multiplexed WDM and IB signals and generates an output signal carried by fibers between the nodes. The booster EDFA switches from an automatic gain control regime upon detecting of at least one of the IB and OB control signals to an automatic power control regime upon loss of both IB and OB control signals. The output signal of the EDFA in the AGC regime has a high power sufficient for transmitting the WDM and IB signals, and has a low power in the APC regime sufficient for transmitting only the IB control signal.

摘要： A laser illuminated projector system is configured with multiple Red, Green and Blue laser sources. The Green laser source has an all fiber master oscillator power amplifier configuration in which pump light is coupled into the output end of the fiber amplifier in a counter-propagation direction rendering the structure of the Green source and therefore projector system compact. The Green laser source is operative to emit signal light pulses at about 1064 nm wavelength with a pulse repetition reaching of up to about 3000 kHz, pulse duration between about a 100 fm to about 100 psec, an average power between 1.5 W to above 30 W, a peak power above 5 MW, a pulse energy exceeding 100 μJ and a beam quality parameter M2 ranging between 1.2 and 1.5. The thus configured Green laser source substantially reduces speckle otherwise visible on the laser illuminated screen.

摘要： A high power fiber laser system emitting a substantially diffraction limited beam with a Gaussian intensity profile includes a single mode (“SM”) neodymium fiber pump source outputting a SM pump light; a seed laser operative to emit a SM signal light at a wavelength greater than that of the pump light; a SM DWM receiving and multiplexing the SM pump and signal lights. The disclosed system further includes a booster fiber amplifier which is configured with a frustoconically-shaped ytterbium (“Yb”) doped core receiving the pump and signal lights and configured with a small diameter input end which supports only a SM and a large diameter output end which is capable of supporting the SM and high order modes (:HOM”). The booster further has a cladding surrounding and coextending with the core, the core being configured for having intensity profiles of respective SMs of pump and signal lights overlap one another so that an overlap integral substantially equals to one (1) along an entire length of the core. The SM of the light signal extracts substantially the entire energy from the pump mode leaving the HOMs without amplification necessary to affect a quality of the diffraction limited beam of the system in a MW peak power range and hundreds of watt average power range.
