Title:
DUAL OPTICAL FREQUENCY COMB GENERATION OPTICAL SYSTEM, LASER DEVICE, AND MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/123719
Kind Code:
A1
Abstract:
In this dual optical frequency comb generation optical system, a first wave guide unit 141, a second wave guide unit 142, a first guide-in unit 161, a second guide-in unit 162, a first reflection unit 121, and a second reflection unit 122 are provided on a common stage 130. Separated from the first wave guide unit and the second wave guide unit is a third reflection unit for reflecting laser amplified light L1 in a D1 direction while reflecting laser amplified light L2 in a D3 direction. The optical path length of the laser amplified light L1 propagating between the first reflection unit and the third reflection unit is different from the optical path length of the laser amplified light L2 propagating between the second reflection unit and the third reflection unit.
