I have a team-shared Coherent Field Mate PM10 (which is great, but is not always available), and a personal LaserBee recommended here . The latter was $200 and worked for 488, 532 and 633 at 200 mW, but could not probe a 730nm beam at 16 mW. The 730 nm beam is what I am after now. The measurements are relative, i.e. I need to know the power drop after bouncing off ~10 mirrors, preferentially having enough accuracy to detect 1-5% drop downstream from every mirror (i.e. <1 mW resolution). Something between $200 and $2K which would not require holding the probe for 1 min for the reading to stabilize would be good (PM10 takes ~<1 sec for this beam).
There is the Coherent LaserCheck for about $500 which claims an 8% accuracy (barely) and <1 sec response time.
Then I just found this chinese unit on ebay for $150 claiming 3% and 1 mW resolution. Has anyone tried it? It does not look like I can post links, but there is only one hit on ebay under " Mini Laser Power Meter Pocket 390~1024nm "
BTW, if anyone has a used working LaerCheck unit they need to unload, let me know!
Cheers!
