Title:
LASER MODULE AND LASER PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/189983
Kind Code:
A1
Abstract:
A laser module 10 is provided with: a photonic crystal surface-emitting laser element 1; a collimating lens array 4 for producing a parallel optical beam; a condenser lens 5 for condensing the optical beam; and an optical fiber 6 which receives the optical beam on one end and transmits the optical beam to the outside. In the collimating lens array 4, an aperture portion 41 corresponding to a collimating lens allows the passage of the optical beam with an energy of not less than 94.0% and not more than 99.5% with respect to 100% of the energy of the optical beam incident on the collimating lens array 4.
