| - | * Design by T. Rosenband (NIST, USA): Mushroom | ||
| - | * geringe Sensitivität der Resonatorlänge auf angreifende Beschleunigungen | ||
| - | |||
| - | * Spacer material: Ultra-low expansion glass (ULE) | ||
| - | * einem technischen Glas, das einen Nulldurchgang des thermischen Ausdehnungskoeffizienten bei Raumtemperatur besitzt | ||
| - | * Dies gewährleistet eine geringe Sensitivität auf temperaturinduzierte Längenänderungen des Resonators. | ||
| - | * Length: 10 cm -> FSR: 1.5 GHz | ||
| - | |||
| - | * Mirror substrates: Fused silica (FS) | ||
| - | * dielektrische Schichtsysteme | ||
| - | * Wavelength: 910-920 nm | ||
| - | * Finesse: F ≈ 600.000 -> Linewidth ≈ 2.5 kHz | ||
