• LS-2149 DPSS


LOTIS TII released new model of DPSS Q-switched YAG laser with relatively high pulse energy at high repetition rate. This laser can substitute flash-lamp pumped YAG laser for many applications.

Diode pumping brings new higher level of performance. Compare with flash-lamp pumped laser with the same output parameters, like LOTIS TII LS-2139 model, new LS-2149 advantages are as following:

  • Compact rigid mechanical design;
  • Long life-time of pump source – 10,000 hours of diode life-time compare with 50 hours of lamp life-time at 100 Hz repetition rate;
  • Perfect beam quality due to much less temperature lens.

Other futures of that laser:

  • Integrated SHG, other harmonics are available by request;
  • Thermo stabilization of Q-switch crystal and harmonic crystal;
  • ThermoCube cooling system;
  • Integrated output energy monitor at 1064 nm;
  • External/internal triggering;
  • Variable repetition rate by dividing Q-switch rate.
