Mini ultrastable laser is available at 1542 and 1064 nm
Designed as an optical reference in field applications, the ORS-Mini ultrastable laser has <2 Hz linewidth, offers frequency stability of <5 × 10-15 in 1 s, and phase noise of -94 dBc/Hz (at 10 kHz offset). It uses a 5 cm high-finesse ultralow-expansion (ULE) cavity, and is available at 1542 and 1064 nm.
