Yes, divergence for red P73 is very bad,you can use a 3x beam expander from sanwu laser,Mailman dropped it off today and I have tons of 18650's so I fired it right up. Yes the spot is horrid but I guess it's the nature of the beast.... it sure does throw out some photons WOW!
Closest laser I have to compare it with is a jayrob 650 that he built for me several years back, the divergence on the jayrob build is light years better but Trinh's beam just smokes it.
The jayrob build used an MXDL host and he was kind enough to include labels ......LPC815-419mA (I'm guessing this is the diode and power)
289 mW (power output ?),
and he used a Meredith glass lens.
What should I buy next?
