Research output: Contribution to journalArticlepeer-review


Internal-mirror 543-nm He-20Ne and He-22Ne lasers are frequency-stabilized to the Lamb-dip of their tuning curves. Frequency stability of 2 × 10-11 and frequency resettability of 4 × 10-9 (or 2 MHz) are achieved. The absolute frequencies of the two lasers are determined by frequency-comparing with an iodine-stabilized 543-nm laser. The isotope shift between 20Ne and 22Ne is measured to one order of magnitude more accurately than the previous result, and the specific-mass-shift for Ne 3s2 → 2p10 transition is also determined.
