Can the second harmonic generation be done efficiently with the right amount of peak power? In this article we will analyze what happens with lower peak power. For example, what if we run the same laser continuously (CW), so the average power might still be one Watt, but the peak power is now also now only one Watt. Can we efficiently generate the second harmonic of that CW beam? Read more and explore SGH with us…
Read MoreWalkoff is different in different situations and with different materials. Second harmonic generation (SHG) and third harmonic generation (THG) can be accomplished in LBO and with other materials. For example, we could use one LBO SHG crystal and one LBO THG crystal. If we have beams with high peak powers then we can use short crystals. However to boost the efficiency of the THG process, we often want to make the crystals much longer. Read on for more about walkoff problems and compensation.
