A coil substrate for wireless power transmission includes: an insulating substrate including a first surface and a second surface; a first wiring portion disposed on the first surface, wherein the first wiring portion includes first spiral patterns and a section in which opposing ends of each of the first spiral patterns are disposed parallel to each other; a second wiring portion disposed on the second surface and including second spiral patterns, wherein opposing ends of each of the second spiral patterns are spaced apart from each other; and conductive vias alternately connecting the first spiral patterns and the second spiral patterns to each other to form coil turns.

Coil substrate

The VECSEL includes: a heat spreader dissipating generated heat; a laser chip that is disposed on the heat spreader and is excited by a pump beam of a predetermined wavelength to emit a beam of a first wavelength; a Second Harmonic Generation (SHG) crystal that is disposed on the laser chip or the heat spreader and converts the laser beam of the first wavelength emitted from the laser chip into a beam having a second wavelength that is one-half the first wavelength; and a planar external cavity mirror that is directly formed on the SHG crystal and has a predetermined transmittance with respect to the beam of the second wavelength.
