Publikováno v: IEEE Photonics Journal, Vol 8, Iss 6, Pp 1-10 (2016)

We have realized a dual-frequency vertical external cavity surface emitting laser (VECSEL) at 1.5 μm. Laser emission of two orthogonally polarized cavity modes is obtained by inserting a birefringent crystal into the VECSEL cavity. We have examined
