Parameter Spec Measurement Technique:

Wavelength = 355nm (Visual confirmation)
Energy = 30 uJ, 160-180 mJ (4025 pulses), 40 uJ (micropulse)

Pulse Duration = 10 ms (Measured at 10 ms on an oscilloscope)

Micropulse Width = 70ps IR, = 50 ps UV (Autocorrelator to measure IR pulse
waveform Temporal Profile - flat envelope)

Measured at 10 ms on an oscilloscope. Micropulse will be measured at
Calmar.

Beam Diameter ~5mm (Burn Paper measurement Spatial Profile)

Beam code measurement 1064 and 355

Beam Divergence ? (Burn Paper measurement)

Repetition Rate = 10 Hz/402.5 MHz

Oscilloscope Shot to Shot Stability = 3% RMS for pulse envelope.

At 355nm from 100 shots

Time jitter = 8 ps (will be measured by Calmar Shot-to-shot stability)

148.8 mJ - 174.6 mJ in 1000 shot (variation 2.6%)

Water - Two pairs of inlets/outlets

Electric Power Supply - Single phase, 220V, 30 A (two connectors)

Dimension: 7ft (L) x 2ft (W) x 1 ft (H)
