Lasers

Copper vapor laser metals have higher average power in the visible spectrum, giant gain medium, high frequency pulses, a small them convincingly, high uniformity of the radiation section. A unique combination of energy, spatial and temporal parameters of these lasers can be used in many branches of science, technology and medicine.

Models and specifications:

  • Pulse repetition — 8 — 16 kHz;
  • Pulse duration — 20 ns;
  • Air cooling;
