High Efficiency Module of Fiber Coupled Diode Laser
Chinese Journal of Luminescence, 2011With the increase of LD application in the field of laser processing,the efficiency of the fiber coupled modular based on diode laser arrays is rather low,which can not meet the need of low costing for laser processing,so it is very important to develop a higher efficiency modular of fiber coupled diode lasers.In this paper,we achieved a higher ...

Efficient Acoustic-Optical Fiber Coupling with Wire Horn Structure
Frontiers in Optics + Laser Science 2023 (FiO, LS), 2023This paper reports on a wire horn structure to enhance acoustic-optical fiber coupling. Compared with the conventional schemes, it was proved to enhance the ultrasonic wave peak-to-peak amplitude coupling efficiency by up to 7.9 times.

Single-mode fiber coupling efficiency with graded-index rod lenses
Applied Optics, 1994Losses are calculated for the single-mode graded-index- (GRIN-) lens coupler. The main advantage of this coupling system is large separation between fibers with small power loss. The excess loss of the GRIN-lens coupler is due primarily to the misalignments of the GRIN lenses and is most sensitive to angular tilt rather than lateral offset or end ...

Develop the fiber coupling efficiency based on SPGD control algorithm
9th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test, Measurement Technology, and Equipment, 2019In the satellite-to-ground laser communication, the beacon light is affected by atmospheric turbulence, atmospheric scattering and atmospheric absorption, so there is a coupling error. And the receiving end of ATP system is affected by random disturbance which lead to the initial coupling place change.

Increased coupling efficiency of fiber coupled modules by smile compensation
High-Power Diode Laser Technology XVII, 2019A technique is experimentally demonstrated which allows for the compensation of the smile of a laser diode bar using a beam transformation system and a telescope array. The beam transformation system consists of a fast-axis collimator and an array of biconvex cylindrical lenses, which rotates each collimated beam by 90°.

Alignment and efficiency-monitoring method of high-power fiber-to-fiber coupling
, 2020High-power fiber-to-fiber coupling is extensively used in fiber laser applications, and its performance is determined by coupling efficiency. We demonstrate a novel method for alignment and monitoring efficiency by detecting backscattering power at the ...

High efficiency fiber coupling to silicon sandwiched slot waveguides
Optics Communications, 2008Abstract The design of a fiber coupler for high efficiency light coupling to silicon sandwiched slot waveguides is reported. The proposed fiber coupler is based on the inverted taper approach. Parameters have been optimized to maximize coupling efficiency for λ = 1550 nm and TM polarization.
