Experimental demonstration of record optical quality factor of (6.3±0.8)×10¹⁰ corresponding to cavity ring-down time of τ360.3em0exμs is made possible by avoiding nonlinear effects in a crystalline whispering gallery mode resonator. We discuss various loss mechanisms in CaF₂ cavities and ways of achieving higher quality factors. Possible applications in quantum optics and photonics are discussed.
