High-stability offset-frequency locking of two lasers using a balanced filter discriminator
Sang Eon Park, Meung Ho Seo, Young-Ho Park +6
We demonstrate a high-stability laser offset-frequency locking technique based on a balanced filter discriminator. The beat note between two 852 nm external-cavity diode lasers is…
