Co spinel Q-Switch crystal

图片
Co:spinel Q-Switch crystal Cobalt-doped magnesium aluminate spinel (Co:MgAl 2 O 4 ) allow the generation of short nanosecond pulse with high peak power around the eye-safe wavelength of 1.5um,perfect for telemetry applications. The absorption spectrum of Co 2+ -doped MgAl 2 O 4  exhibited a broad absorption band in the wavelength range of 1200–1600 nm, which indicated that Co 2+  ions substituted for the tetrahedrally coordinated Mg 2+  ions in the MgAl 2 O 4  lattice. Passive Q-switching of solid-state lasers with solid-state saturable absorbers is a very attractive Q-switching technique because it allows to develop compact and low cost laser sources of nano and sub nanosecond pulses far various applications Co spinel——saturable absorbers for the passive Q-switching of solid-state lasers operating at eye-safe wavelength of 1.5 μm Lasers emitting at 1.5µm are of great interest for several industrial applications. This interest is, first of all, due to eye-safety of 1....

Why choose phosphate glass

图片
Optical properties of the host medium such as uniform and inhomogeneous expanding as well as thrilled and ground state absorption cross sections are figured out by the structure. Fused silica is an extremely helpful host for applications where very long amplifiers can be utilized. It has high toughness, low development and also good optical transmission properties along with higher chemical security and better mechanical residential or commercial properties than phosphate glasses . Though tiny silica laser tools have actually been revealed to function, silica based systems suffer from the rare earth focus being limited by focus quenching (or "clustering"), low solubility and various other undesirable impacts. Much more complex silicate glasses can conquer several of these issues however these sorts of glasses still have actually low Er stimulated emission cross sections and also reduced laser efficiencies at 1.54 μm. Phosphate glass is a prominent laser oscillator/amplifier ...

Nd: YAG principle

图片
Nd: YAG crystal product, likewise called neodymium-doped yttrium aluminium garnet crystal, is a sort of laser tool crystal with good thorough efficiency for solid-state laser. YAG has been and will continue to be the extra widely utilized laser crystal; whether strong state or light pump, CW or pulse, it has an one-of-a-kind mix of qualities conducive to laser operation. Nd: YAG pump tube of using triggered compounds crystal generally krypton light or xenon lamp and pump broadband discharge range is a continual range, however only a few fixed spectrum top absorbed by neodymium ions, so the pump is just a small part of the advantageous spectrum energy is used, and also most are not taken in spectrum power is transformed to heat, so the power utilization proportion is low. The Nd: YAG absorption range ranges from 0730 to 0760 microns and also 0.790 microns to 0.820 microns. The spectrum can be taken in, and after that it will trigger the atom to shift from reduced to higher power degre...
