Separate phase-locking and coherent combining of two laser diodes in a Michelson cavity. Presented at High-Power Diode Laser Technology and Applications XIII

We describe a new coherent beam combining architecture based on passive phase-locking of two laser diodes in a Michelson external cavity on their rear facet, and their coherent combination on the front facet. As a proof-of-principle, two ridge lasers... Read More about Separate phase-locking and coherent combining of two laser diodes in a Michelson cavity.

Parity-time symmetric coupled microresonators with a dispersive gain/loss (2015)
Journal Article
