摘要：

We present the results of nonlinear transmission in various ordered and disordered mesophases of liquid crystals, and demonstrate that in bulk or guided wave geometry, they are capable of clamping the transmission of pulsed or cw lasers to below the Maximum Permissible Exposure level of eyes and optical sensors in the entire visible - infrared region.
