Product Description:
YAG Fiber crystal light brazing transmittance 80% 25μm 100μm can be
used for optical brazing sensors
YAG optical fiber Abstract:
Monocrystalline yttrium aluminum garnet (YAG) fiber, which has
better physical properties than amorphous silica and has a higher
output power. These fibers support a whole new range of
applications, including materials processing and medical lasers.
There are several ways to develop high-power (kilowatt) lasers.
Bulk single crystals are widely used due to their excellent thermal
conductivity, efficiency, and mechanical resistance.
Our customizable YAG Optical Fiber, made from premium Yttrium
Aluminum Garnet (YAG) material, is designed to meet the
requirements of high-performance optical systems. With a
transmittance of over 80% across a broad spectral range from 400 nm
to 3000 nm, this fiber is ideally suited for applications that
demand precision and reliability in the transmission of light or
energy. With diameters ranging from 25 μm to 500 μm, the fiber can
be customized for use in various optical systems, including
high-temperature sensors, tunable lasers, and advanced
communication systems. The exceptional physical and optical
properties of the YAG fiber make it a superior choice for
industries that rely on the highest standards of performance.
YAG optical fiber Properties:
This YAG Optical Fiber is engineered for a broad range of demanding
applications, thanks to its superior material properties. The
following highlights some of the key characteristics:
- Beam quality: The key aspect in which Nd:YAG is superior to fiber
lasers is the quality of the beam. Essentially, laser marking beam
quality is the specific term for the M2 value, which is usually
given in the laser specification. The Gaussian beam has an M2 of 1,
allowing for a minimum spot size relative to the wavelength and
optics used.
- The optimal beam quality in the Nd:YAG laser marking system is an
M2 value of 1.2. Fiber-based systems typically have an M2 value of
1.6 ~ 1.7, which means a larger spot size and lower power density.
For example; The peak power of fiber lasers is in the range of
10kW, whereas the peak power of Nd:YAG lasers is in the range of
100kW.
- Basically, better beam quality will result;
- small line width,
- Sharper contours,
- Higher marking speeds (due to high power density), as well
- Deeper engravings.
- Good beam quality can also provide a better depth of focus compared
to lasers with lower beam quality.
