Title:
LASER DEVICE AND METHOD FOR GENERATING LASER LIGHT
Document Type and Number:
WIPO Patent Application WO/2021/010128
Kind Code:
A1
Abstract:
A laser device 1A is provided with a light source unit 10A and an optical multiplexing unit 21. The light source unit 10A outputs first laser light L1 and second laser light L2 having a wavelength different from that of the first laser light L1, onto respectively different optical paths. The optical multiplexing unit 21 is optically coupled with the light source unit 10A and multiplexes the first laser light L1 with the second laser light L2 to generate burst pulses at a frequency corresponding to a difference between the wavelength of the first laser light L1 and the wavelength of the second laser light L2. In the light source unit 10A, the wavelengths of the first laser light L1 and the second laser light L2 are set, or can be set, in advance so that the frequency of the burst pulses becomes 1 GHz or above. Thus, a laser device and a laser light generating method capable of generating burst pulses having a high repetitive frequency of 1 GHz or above can be provided.
