Have bought 3 pieces. Quality of beam and power are GOOD Divergence can be optimised. Two of these lasers are TEM00 (95%) Beam is polarised.
Watch out, infrared energy 808 and 1064nM is mixed with the 532green beam, the 1064 has the same divergence , the 808nM beam has a big divergence and is not really a problem. (have measured this with professional laserpowermeter and filters and I have viewed the IR beam divergence with Night Vision equipement.
Strange rules in USA and other nations, this is a nasty laser wich can blind you in a split second but can be delivered in USA etc.
For Scientists with huge apsirations and low budget , : buy several of these lasers, the chance you get a laser with Laboratory class beam (have to apply IR filter)is big. You can apply Tec 23 Centigrades for optimal resonator convertor efficiency (Nd YVO4/KTP) and longer life for the 808 LD.
