The principle of diode-pumped solid-state crystal laser
Energy is pumped into the rare earth crystal forming the active medium of the laser by means of luminous semiconductor diodes. Either a transport optical fibre is placed between the diodes and the crystal or the crystal is excited directly by the laser diodes. The crystal and its geometry is designed in such a way that energy is gradually accumulated in the crystal, which is then processed by deflection mirrors and the scanning head lens optics. The focused laser beam can then be used to mark, engrave, drill or otherwise modify materials responsive to a given wavelength of laser radiation.
Advantages of diode-pumped solid-state crystal laser

We supply diode-pumped solid-state crystal lasers – in power ranges from 4 to 20W
Examples of diode-pumped solid-state crystal laser applications
- Laser engraving – metals, plastics.
- Laser marking – plastics, metals.
- High power diode lasers (1 kW or more) are used in industry for welding metals and for hardening.
Diode-pumped solid-state crystal lasers are also used in medicine (ophthalmology, dentistry), defence industry, biology, etc.
At the customer’s request, we also offer complex solutions for a single-purpose machine tailored to the exact application required. In our application laboratory, we are happy to make samples directly on your parts and advise you on the optimal solution.
