NL740 tunable pulse duration NdYAG lasers

The main feature of the Ekspla  NL740 series is the output of ultra-stable tunable duration (2 – 10 ns) narrow bandwidth nanosecond pulses based on temporally driven CW diode laser seeder and amplification stages.

Start of the system is the single mode DFB laser with temporal output power modulator. Then light is amplified in diode pumped regenerative amplifier in order to reach energy sufficient to amplify in double pass diode pumped amplifiers. Power amplifier is a chain of double pass amplifiers where pulse is amplified up to required energy. Before amplification spatial beam shaping is employed in order to get flat top shape at the output. The harmonic generators are based on angle tuned nonlinear crystals placed in a heater. Read more.
