Insulators for lasers
Advanced ceramics are widely used in laser systems due to their combined properties of very good electrical insulation - high voltage and high current - and resistance to gas and plasma corrosion. Their resistance to temperature variations, to high temperatures, as well as their very low thermal expansion make them reliable materials to manufacture precision components.
MORE INFORMATION
Most of laser systems integrate insulators made of advanced ceramics :
- solid-state lasers (Nd-Yag..)
- gas lasers (excimer lasers, CO2 lasers….)
- fibre lasers
- semiconductor lasers
- diode lasers
- high-power laser diodes
In view of their properties ceramics are used to manufacture insulators of various dimensions and geometries, resistant to gas corrosion and plasma discharge :
- high-voltage insulators
- ionisation electrode plates
- insulators for electrical feedthroughs
- corona insulators
- discharge tubes
Advanced ceramics are widely used in laser systems due to their excellent electrical insulation, resistance to gas corrosion and their low thermal expansion.
The most interesting grades for laser applications are :
- High-purity alumina (Al2O3) - 96 to 99,8 %
- Aluminium nitride (AlN)
- Boron nitride (Bn)
- Macor ®
