Abstract
An energy collector is used to assist a laser coupling process by reducing the amount of output power of a laser that is used to modify a device attaching element. The energy collector includes an energy collector tip configured to be placed proximate to a device attaching element during the laser coupling process. The energy collector tip is configured to receive laser energy reflected from the device attaching element during the laser coupling process and is formed from a material that converts this reflected energy to heat. Sufficient thermal coupling is created between the energy collector and a surface to provide a conductive pathway for the energy, which has been converted to heat, between the energy collector and the device attaching element.
