Patent ID: 11906668
Assignee: BEIJING VOYAGER TECHNOLOGY CO., LTD.
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 10:
11. An apparatus for emitting laser light, comprising:
a first laser source configured to provide a first laser beam having a first wavelength equal to or above 1,100 nm;
a second laser source configured to provide a second laser beam having a second wavelength different than the first wavelength; and
a wavelength converter configured to convert the first laser beam and the second laser beam into a converted laser beam having a third wavelength below 1,100 nm, wherein the wavelength converter comprises:
a nonlinear optical material configured to perform optical frequency mixing of the first laser beam and the second laser beam, and
a temperature controller configured to set a temperature of the nonlinear optical material based on the third wavelength of the converted laser beam,

wherein the first laser source and the second laser source are separate.
