The LS-2138 incorporates all advantages of LS-2136 and LS-2137 lasers with a pulse repetition rate up to 100 Hz, small divergence, output energy up to 220 mJ.



The unique design of the power supply and laser cavity provides high output parameters and reliability. The totally selfcontained cooling system with water-to-air heat exchanger allows laser operation in different environment conditions.

LS-2134N, LS-2145N, LS-2134TF, LS-2145TF

The LS-2134N and LS-2145N are improved models of our well known compact laser series LS-2134, LS-2145.


LS-2147A is new improved model of LOTIS high power lasers. Laser consists of two independent modules: oscillator and power amplifier.

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.

LS-2146 DPSS

LOTIS TII introduce a new high-energy diode pumped laser. The laser has a built-in second harmonic and can be supplied with external harmonic generators (355, 266 and 213 nm).


LS-2151 is an actively mode-locked and Q-switched MOPA laser that incorporates all solid state master oscillator (MO), two-pass amplifier (PA), built-in second harmonic generator (SH), remote control from a PC through an RS-232 or USB interface.


The fifth harmonic generator (213 nm) can be employed with LS-2136, LS-2137 lasers as well as with those of customer.


LOTIS TII lasers can be equipped with harmonic generators (HG) for radiation conversion of fundamental and second harmonic into the UV-region.
