Re: FEELER: XPL Lasers (RG:Y, RB:M, high-power 532s, etc)
Excellent points---proceed with caution until all the details both positive and negative, of these units become known. Important things like what the warranty actually covers, continous wave or fast pulsed wave output, and especially Duty Cycle are important questions that need answers.
It's the low prices that no other company even come close to that causes concern the case being usually if it is too good to be true it usually is. 500mW@ $107, 700m @$223, 1W@$243, and 1.5W @$325 even lower with LPF discount, seems incredibly low compared to any other laser maker's offerings that causes some concern. Example: I would not want a 1.5W 532nm with 10 to 20 second on duty cycle at any price.
I guess, what is it that XPL 532nm lasers are not and don't do compared to other lasers available is more the question.
As you say, it may well be entirely all be legit ( hope that it is)
Right now all we have to go on is Sta's 500mW 532nm review wherein the peak output power was good/overspec but stable output was TEM02, not TEM00 as stated in the specs so....??
Yep - it's something that needs clarified.
Just because you can get 2W out of some crystals doesn't mean they can actually survive the required input power for any length of time (which would explain the lack of warranty there if this is the case). Also possible that the pump diodes are being severely over driven to reduce costs - which would again explain the lack of a warranty on the "diode"... Generally these things are covered under warranty - diodes/crystals are actually really quite reliable when run at spec with proper electronics driving them and proper cooling/mounting - as long as you aren't going around dropping the laser...
Imagine you bought a 2W labby from Viasho and they told you that if the diode breaks during the warranty period that you are SoL? Of course that product would be way more expensive, but the point stands. It'd be like buying a new vehicle that doesn't have the power-train covered under warranty...
May all very well be entirely legit (and I hope it is!) - but it's best to proceed with caution before dropping so much money on what is basically, at the moment, an unknown.
