Laser spectroscopy of color centers in yttrium aluminum garnet
Nd:YAG lasers have become ubiquitous as tools for spectroscopy, materials processing, and medical care. It is well known by crystal growers that lattice defects in Nd:YAG can stifle laser efficiency, but to date very little has been done to isolate and characterize individual YAG defects. Knowing …

Improving the efficiency and threshold current of photonic crystal vertical-cavity surface-emitting lasers
… to achieve high power, low threshold, and high efficiency single mode VCSELs. Various mechanisms that affect the differential quantum efficiency and threshold current of the proton-implanted and oxide-confined photonic crystal vertical-cavity surface-emitting lasers (VCSELs) are studied. Three …
