Laser Drilling

Materials resistant to high temperatures, such as Hastelloy, tungsten, molybdenum, and all types of precious and non-ferrous metals, are suitable for laser drilling. Ceramic materials such as sapphire, ruby, diamond, and aluminum oxide, as well as related materials, can also be drilled with a laser.

In single-pulse drilling, a single laser pulse with relatively high pulse energy creates the hole. This method allows for the rapid production of many holes. It is often used to manufacture filters with thin walls up to approximately 1 mm thick.

In percussion drilling, the hole is created by a series of successive laser pulses with shorter pulse durations and lower pulse energy. This drilling method produces deeper and more precise holes than single-pulse drilling. Percussion drilling allows for hole diameters ranging from 0.02 to 0.4 mm and drilling depths of up to 10 mm.
