N2 - We report on the first observation of intracavity laser cooling inside of a vertical external-cavity surface-emitting laser (VECSEL). A Yb:YLF crystal is placed under Brewster angle inside the cavity of an InGaAs quantum well VECSEL emitting around 1030 nm. With the crystal in air, we observed cooling by about 0.5 degrees. By placing the sample and cavity end mirror inside a vacuum chamber, with the window also at Brewster angle to the laser mode, cooling by 20 degrees has been realized. Furthermore, the development of a compact and efficient integrated cryocooler device is underway.
