Overview
Specifications
| Parameter | Value |
|---|---|
| Bonded Crystal | YAG+Nd:YAG, YAG+Cr:YAG; GdVO4+Nd:GdVO4; YVO4+Nd:YVO4; YLF+Nd:YLF or other dopants. |
| Nd:YLF | Rod diameters from 2mm to 10mm, lengths from 1mm to 150mm; Nd doping concentrations 0.4 and 1.2at%; Tm:YLF, Pr:YLF, Ho:YLF also available |
| Nd:YLF | Neodymium-doped yttrium aluminum garnet (Nd:YAG) is the earliest and most famous laser crystal. Owing to its many excellent fundamental properties, Nd:YAG is still widely used in near- and far-infrared solid-state lasers and their frequency-doubling and frequency-tripling applications. |
| Yb:YAG | Yb:YAG crystal is a solid-state laser gain medium with great development potential. Compared with traditional Nd-doped systems, it is more suitable for diode-pumped systems. Compared with the commonly used Nd:YAG crystal, Yb:YAG crystal has a wider absorption bandwidth, which reduces the temperature management requirements in diode laser applications, a longer upper laser level lifetime, and a thermal load per unit pump power that is 3-4 times lower. At 1030nm, Yb:YAG crystal can well replace Nd:YAG crystal used at 1064nm, and its second harmonic at 515nm can replace Ar-ion lasers emitting at 514nm. |
| Er:YAG | Er:YAG crystal is an excellent 2.94μm laser crystal. Among all wavelength bands, this laser wavelength is easily absorbed by water and hydroxyapatite and is considered an excellent surface-cutting laser. It is widely used in laser medical systems and other fields, such as dentistry (hard tissue) and orthopedics. |
| Nd:YLF | Nd:YVO4 (neodymium-doped yttrium vanadate) crystal is a laser crystal with excellent performance, suitable for laser-diode-pumped lasers, especially low and medium power lasers. Available doping concentrations: 0.1-3% |
| Nd:YLF | Nd:GdVO4 (neodymium-doped gadolinium vanadate) is an excellent laser crystal with properties similar to the neodymium-doped yttrium vanadate single crystal (Nd:YVO4). It has excellent physical, optical and mechanical properties and is one of the ideal laser gain media for laser-diode-pumped all-solid-state (DPSS) miniature lasers. Available doping concentrations: 0.1%, 0.2%, 0.3%, 0.5%, 0.7%, 1.0%, 3%, etc. |
| Nd:YLF | Neodymium-doped potassium gadolinium tungstate crystal (Nd:KGd(WO4)2 or Nd:KGW) is an excellent laser gain material with a low laser oscillation threshold and a higher emission cross-section. Standard concentrations: 3%, 5%, 8% |
| Yb:YAG | Ytterbium-doped potassium gadolinium tungstate crystal (Yb:KGd(WO4)2 or Yb:KGW) is an excellent laser gain material with many important advantages over the widely used Nd3+-doped materials. Standard concentrations: 5%, 10% |
| ErCrYSGG | Er,Cr:YSGG crystal with Cr3+ as sensitizer ion and Er3+ as active ion has become one of the most promising laser crystals in recent years. |
| Ti:Sa(800nm) | Ti:Al2O3 (titanium-doped sapphire) laser crystal is currently the core material for femtosecond ultrashort pulse lasers and petawatt-class high-power laser technology. This crystal features a tunable wavelength (660-1200nm), a wide emission bandwidth (about 600nm), a large emission cross section, high thermal conductivity and excellent physical and chemical properties, making it the most widely used tunable laser crystal and the most important gain medium for ultrafast, ultra-intense high-power laser operation. |
| Special Crystals | GSGG / Nd:GSGG / Er:YSGG / Er:Cr:YSGG / Yb:Ho:Lu:YAG / LGS / GSGG / GGG / Nd:GSGG / Er:YSGG / Yb:Ho:Lu:YAG / LGS, etc. Special product processing: irregular-shaped crystals, curved crystals, and other experimental custom crystal processing |
