Abstract

A laser module includes: a photonic crystal surface-emitting laser element; a collimating lens array for producing a parallel optical beam; a condenser lens for condensing the optical beam; and an optical fiber which receives the optical beam on one end and transmits the optical beam to the outside. In the collimating lens array, an aperture portion corresponding to a collimating lens allows 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.
