Hi,
These are dual 60 mW combined diode lasers. The diodes are TEC cooled. The hours on these may be fairy high but they work to spec and were about $10K new. Add a collimator lens and they might be great for light shows; they have fast modulation capability. Also the seller Dan is a great guy and if the laser is not right you guys have no worries. I suppose people could replace the diodes with 120 mW ones and make a 1/4 watter but how to make the adjustments in current I don't know. For the price I don't see why these did not sell long ago. Buy them or be sorry. Phil
