Strain-induced improvements on linear and nonlinear optical properties of SrB4O7 crystal

AIP Advances, 2012
Although the high nonlinearity, strontium tetraborate crystal SrB4O7 is angular non-phasematched in UV SHG process due to its low birefringence. In this Letter, we revealed that its birefringence can be significantly enhanced by uniaxial strain based on ...
