Hi chaps,
I have something very similar to a large frame ion, in terms of beam quality and output power, and wanted to ask the experts // people with direct experience of doing this, how best to fibre couple such a beam? Planned delivery will be to a remote scan head (20-50m away).
In the past I've coupled a 10W OPSL 532nm before with 50µm with a 5-axis launcher, with correct peaking-procedure, and wasn't impressed with the coupling efficiency.
Does anyone have any recommendations for such quality beams, M^2 <1.4, Po = ~30W, specifically w.r.t. what diameter fibres, and coupling / decoupling lenses?
Is there any possibility to deliver the output and maintain very close to the input beam spec at high efficiencies (>70%)? Dia 2mm, 0.8mRad?
Thanks!
Dan
