Abstract: The second harmonic generation in KDP and LiNbO₃ crystals exposed to tightly focused radiation from a Cr:forsterite laser is studied. The negative influence exerted on this process by a plasma produced due to multiphoton ionisation in the focal region at laser pulse intensities above 10¹³ W cm^-2 is discussed.
