…to come. Since
the Azure uses standard single-phase electrical
power, it can lower your utility costs. For this
reason, the Fiber Bragg Grating Industry is taking a close look at the Azure. Its high conversion
efficiency--from green to deep-UV--extends
the lifetime of the…

…of embedded Yb ions,
which re-emit with nearly 100 percent
quantum yield.
Here, they use a laser diode controlled
by a fiber Bragg grating (FBG) tuned so
that the narrowband excitation light is
red-shifted from the absorption line center. The long excited-state lifetime…

…3oC, equivalent to 10 GHz.
In summary, in this paper we report a diode laser array linewidth-narrowing technique
using the volume Bragg grating. Because of the use of a thick VBG, low smile DLA, and high
quality AR-coating on the emitters' front facets, a bandwidth of 7-GHz from ECDLA…
