High Power 808nm VCSEL is the perfect source to replace QCW laser bar for Nd:YAG side-pumping. It has very low wavelength shift, high operation temperature, 10+ times longer life time and much lower cost per Watt. LASERCONN designed multijunction VCSEL to reach similar power density to 3-Bar Stacks for direct replacement as following:
