Yb:YAG Laser Crystal Rod
Product Specifications/Features
Main Advantages of Yb:YAG Crystals
Very low fractional heating, less than 11%
· Very high slope efficiency
· Broad absorption bands, about 8nm@940nm
· No excited-state absorption or up-conversion
· Conveniently pumped by reliable InGaAs diodes at 940nm(or 970nm)
· High thermal conductivity and large mechanical strength
· High optical quality
Yb:YAG crystal is an excellent laser-active materials and more suitable for DPSS (diode-pumping solid state )
lasers
than the traditional Nd-doped systems. It can use be pumped 0.94μm and
0.97μm laser diodes for pumping which are much cheaper than 0.81um
diodes and can get higher quantum efficience. Yb:YAG crystal has also a
much larger absorption bandwidth to reduces thermal management
requirements for diode lasers, a longer upper-state lifetime, three to
four times lower thermal loading per unit pump power compared with the
commonly used Nd: YAG crystal. Yb:YAG crystal (1030nm) is expected to
replace Nd:YAG crystal (1064nm) for high power DPSS lasers and its
second harmonic ( 515nm ) may replace large volume Ar-ion lasers (
514nm)

Chengdu Dongjun laser Limited by Share Ltd was founded in April 27,
2001, completed in 2010 the shareholding system reform, the company's
total share capital of 60000000 shares, shareholders by the Dongguan
Chengdu Group West complex science and technology limited company and
natural person shareholder Dongjun Group Co Ltd,. High and new
technology enterprise Dongjun laser is the largest specialized in laser
crystal materials and other artificial crystal materials research,
development and production of the. Company is located in Chengdu Pujiang
eco industrial park, covers an area of 112 acres, the total
construction area of 22000M2.
Dongjun laser Limited by Share Ltd is the key enterprise of new
materials of national high-tech enterprises in Sichuan Province, the
construction of innovative enterprises, Chengdu city. The development of
high technology and products is the company's core competitiveness, the
company since its inception, has a number of invention patents and
utility model patents in the laser crystal and sapphire crystal series
crystal research and development.
The company passed the ISO9001-2000 quality system and GJB9001 standard quality system certification.
One, in YAG crystal
Dongjun laser in YAG crystal doped, doped, doped technology repeatedly
won the national science and technology achievement award, with
independent intellectual property rights, especially in the neodymium
doped yttrium and cerium gold ore laser crystal rod, won the two prize
of national scientific and technological progress, in the domestic
leading level. With the development of the company, the company
increased R & D investment, a major breakthrough in the development
of YAG laser crystal are obtained, linear optical crystal and
scintillation crystals, the formation of a stable production capacity,
and has made dozens of invention patents and utility model patents, has
provided a powerful guarantee for the sustainable development of the
company's products.
A series of laser crystal material Dongjun laser production are widely
used in military and civil fields, the company has a rich variety of
products, in the production of laser crystal material can provide:
Nd:YAG, (Nd:Ce): YAG, Cr4+: YAG, Er:YAG, Ce:YAG, Yb:YAG, (Tm.Ho): YAG,
(Tm.Ho.Cr): YAG crystal, Nd:YAP, Er:Glass, YOV4, Nd:, YOV4 and other
types, different doping concentration, but also have the ability of
optical processing technology first-class, can be customized according
to the customer requirements, production of various kinds of crystal,
crystal slab, bonding crystal, crystal products such as thread.
Two, in terms of sapphire
Sapphire crystal growth equipment and technology decreased induction
heating molybdenum crucible Dongjun laser company independent
innovation, realize the principle of innovation, technology and process,
obtained two invention patents and two utility model patents, in 2010
passed the provincial appraisal of achievement of science and
technology, the technology has been in batch production.
We can provide large quantity of C, A, R to to to, M to 2 ", 4", 6 "Sapphire ingot, wafer and special optical window film.
In 2010 December, Chengdu Dongjun laser Limited by Share Ltd two new
plant put into use, the company sapphire crystal industrial projects
into the accelerated implementation stage, the Dongjun laser has become a
key enterprise of domestic LED sapphire substrate production.
