We have completed the V-BASIS packages for three
entire backplanes (gt240 kWpeak optical pump power)
Split backplane holds 36 V-BASIS tiles
3 backplanes are complete, 4th backplane by
December

The diode backplane has the required brightness
and thermal performance
Fast axis brightness
Slow axis brightness
The diode backplane provides suitable mechanical
tolerance and cooling

V-BASIS packages
Remember, our original modeling specified a
gaussian spread with a FWHM of 8 nm. While
this distribution is not gaussian it is narrower
overall than we had originally anticipated.
