Title:
GLASS BLOCK, OPTICAL FIBER TERMINATION STRUCTURE, LASER DEVICE, AND LASER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/207902
Kind Code:
A1
Abstract:
The present invention provides a more compact glass block that minimizes the possibility of Stokes oscillation. The glass block (11), which is shaped as a column, outputs laser light from an emission surface (11o) when the emission surface (21i) of a delivery fiber (21) is connected to the incident surface (11i) of the glass block. The emission surface (11o) of the glass block (11) is configured so that the reflectance with respect to Stokes light is greater than the reflectance with respect to laser light.
