Low Noise, High Gain: YDFA's Path To Becoming a "Hidden Champion" in The 1.0μm Band

-

 This is a Ytterbium-doped fiber amplifier. High power YDFA has built-in cooling fan. Here is a desktop type, customizable module fiber amplifier.

The working mode can be set to ACC or APC. Click the Mode area to switch the working mode. In ACC(Automatic Current Control) mode, set the operating current. In APC(Automatic Power Control) mode, set the output power. Use the up and down arrow keys on the right side of the screen to adjust the corresponding parameters. We can also click 'Power Set' or 'Current Set' to enter the value you want.


Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with semiconductor laser, and is used to amplify optical signals in the 1030~1080nm band. The output power is continuously adjustable, and it has the advantages of high gain and low noise. The desktop YDFA is convenient for experimental operation, and the user can adjust the pump current and output power through the panel. A more compact modular YDFA is also available to facilitate user system integration. Both the desktop YDFA and the modular YDFA can support host computer software control and serial port command control.



The core of YDFA is ytterbium-doped fiber. An external pump laser (typically with a wavelength of 980nm or 915nm) injects energy into the fiber, causing ytterbium ions to transition from their ground state to a higher energy state. When signal light enters the ytterbium-doped fiber, the high-energy ytterbium ions undergo stimulated emission, transitioning back to the ground state and releasing photons of the same wavelength and phase as the signal light, thus amplifying the signal. The ytterbium ion energy level structure is suitable for high-power pumping, enabling kilowatt-level output, and is commonly used in laser processing and medical fields. Low noise and high gain: Compared to EDFA, YDFA has advantages in low noise figure and high gain in specific wavelength bands. Through its high power and specific wavelength band advantages, YDFA complements the shortcomings of EDFA in industrial and communication fields, becoming an important branch of fiber amplifier technology.

Femtosecond lasers extend glass cleaving to mixed materials

-
Filamentation cutting is a relatively new process that uses ultrashort-pulse (USP) lasers to cut a wide range of glass substrates, from soft borosilicates to chemically hardened glass used in smartphone displays. Among the advantages of filamentation cutting are the ability to produce curved shapes and cut-outs, cutting speeds up to 2000 mm/s, and superior stress-free edge quality, which eliminates the need for post-processing. The high peak intensity created by a focused USP laser produces self-focusing of the beam because of the nonlinear optical Kerr effect, further increasing power density until, at a certain threshold, a low density plasma is created in the material. This plasma lowers the material refractive index in the center of the beam path and causes the beam to defocus. If the beam focusing optics are properly configured, this focusing/defocusing effect can be balanced to periodically repeat and form a stable filament, which extends over several millimeters in depth throu...
