short pulse nanosecond laser Leo by photon energyDue to their excellent beam profile and pulse energy rating LEO lasers are especially suited for applications which require a high level of precision like the generation of high definition patterns, filigree engravings or trimming of electronics. The air-cooled, low maintenance lasers stand out because of their robustness, they are easy to operate and low cost.
LEO lasers are diode pumped solid state lasers (DPSSL) with an acousto-optic modulator as a q-switching device. By adjusting pulse energy as well as pulse repetition frequency to the particular application, the mutable pulse repetition frequency enables the user to fully benefit from the whole range of the output power. This is especially useful when not only precision and quality but also process speed has to be taken into account.

Depending on the application LEO-lasers are available as Nd:YAG or Nd:Vanadate. Of course the laser is protected against optical back reflections.
