D iffraction properties o f t otal internal reflection (TIR) grating etched in fused silica under second Bragg angle incidence are investigated The grating profile parameters are optimized using the rigorous coupled wave analysis (RCWA) With the optimized results diffraction effi ciencies of 99.68% and 99.87% can be obtained for TE and TM polarization s in the reflected 2nd order, respectively The presented grating s under second Bragg angle incidence have advantages of high efficiency of TIR high damage threshold of fused silica and important broadband property for operation, which should be useful elements for numerous optical applications, especially for high power laser syst ems..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
