Abstract

We demonstrate the improved purity of the emission spectra of a Yb³⁺-doped Y₃Al₅O₁₂ laser with resonant grating mirrors. When the two mirrors’ principal axes are twisted, both multiple longitudinal mode emission and dual polarization emission are suppressed. The proposed design enables a compact single mode laser, replacing more complex designs usually needed to achieve that goal.
