you can read it all or go to pg. 13 final conclusions.
" The most essential improvement would be to minaturize the device with a laser diode design rather than it,s current solid state design."
"When higher power green laser diodes become available this tech. should be further explored."
This was in 2001, LNGT has the higher powered pumped tunable lasers,minaturized design and the patents etc. but you already knew this before you posted that article from 1998.
