Double pulsed Q-switched Nd: YAG lasers are designed to provide highly stable, nanosecond pulsed IR, green and UV radiation for Particle Image Velocimetry (PIV), Laser Induced Breakdown Spectroscopy (LIBS) and other kinetic applications.

These compact double pulsed lasers (DPL) are designed with a unique laser head: two independent laser resonators pumped by a single flash lamp are integrated in one  laser emitter. A single power supply and cooling unit (with water-to-air heat exchanger) are used in the DPL. Ease of use is provided through multiple triggering:
• single-shot push button trigger and continuous internal trigger from remote control,
• external TTL trigger,
• computer-controlled laser operation via RS-232 port.

These DPLs combine the reliability and rigidity of LS-2131-2134 lasers with operation in dual pulse mode: two output pulses of equivalent energy; polarization and high beam uniformity.  Dual output ports allow each oscillator to operate independently when necessary. 

DPL can be fit with harmonic generators and tunable solid state lasers.
LS-2134D-Cx, LS-2145D-Cx – improved models from the family of LOTIS TII double pulsed Nd:YAG lasers generating two pulses: visible and the ultraviolet. 

Standard configuration LS-2134D-C3 has at output the second harmonic (532nm) and third harmonic (355nm).
