Abstract

Characterizations of low-loss mirrors by measurements of cavity-decay time and of cavity finesse are reported near 850 nm. The lowest observed mirror loss is 1.6 × 10−6 (transmission plus absorption and scatter), which corresponds to a reflectivity of 0.9999984 and to a cavity finesse of 1.9 × 106.

Transmitted power Pt monitored with detector D versus time t. The initial rise in Pt for t < 0 corresponds to the filling of the cavity as the cavity length scans into resonance. At t = 0, Pt crosses a predetermined threshold and the input laser is switched off by the AOS in Fig. 1. The subsequent decay of the intracavity field is then exhibited for t > 0. This curve is an average of 100 single decays for an excitation wavelength of 852 nm

Decay time τ for intracavity power versus excitation wavelength λ. The right-hand scale gives the inferred loss L = d/cτ, with d = 4 mm as the cavity length. The point at λ = 837 nm was taken at PMS with a diode laser as discussed in the text and is referenced only to the scale for L.
