ABSTRACT:
A high-power optically end-pumped external-cavity semiconductor laser is provided having a laser chip including an active layer and a distributed Bragg reflector (DBR) for emitting light of a fundamental wavelength; an external mirror spaced apart from a first surface of the laser chip and forming a cavity resonator with the DBR; a second harmonic generation (SHG) crystal positioned between the external mirror and the laser chip; and a micro-lens integrated heat sink dissipating heat generated by the laser chip and bonded to a second surface of the laser chip to focus a pumping beam to be incident on the second surface of the laser chip.
