Q-switched Nd:YAG Lasers
The family of LOTIS TII Q-switched Nd:YAG lasers includes devices with different output pulse energy, duration from 5 nanosecond to 24 nanosecond, beam divergence and repetition rate. They are usually equipped with build-in or external converters up to fifth (213 nm) harmonic of fundamental laser frequency.
Application of mirrors with variable reflection coefficient in certain laser models provides the excellent beam quality with good conversation into harmonics.
Double-pulsed Q-switched laser exhibits the precision delay between two output pulses with 1 ns accuracy and can be used in laser spectroscopy and velocimetry.
Reliable and stable LOTIS TII lasers are simple in operation, supplying with the convenient remote control and computer interface.
