• Adjust the 4HG crystal angle to maximize the output energy.
• Adjust the wave plate on the input to the SHG housing to maximize
the energy.
• Adjust the SHG crystal angle to maximize the output energy.
• If the optional attenuator is installed, ensure that the attenuator knob
is rotated fully clockwise to the maximum energy/minimum
attenuation setting.
• Check the harmonic crystals and housings to ensure that all surfaces
are clean and undamaged.
• If none of the above work, check the 532 nm energy, then the 1064
nm energy.
