Double pulsed Nd:YAG lasers

LF121 & LF123

Double pulsed Nd:YAG lasers LF121 and LF123 are used as dual laser pulse source with temporal adjustment between the pulses. These lasers are ideal source for Laser Induced Breakdown Spectroscopy.

• Super-stable rigid rod resonator design
• Capability of operation at 1064 nm, 532 nm, 355 nm
• Adjustment of delay between pulses in the range 0 - 150 µs
• Control of laser output parameters and laser units
• Long-term stability of output parameters
• High stability of self-contained cooling system 
• < 1 ns jitter
• Thermal stabilization of all crystals
• Output energy variation in each channel is possible with polarization attenuator (option)
