Hi,
Sam and I have a really nice low hour Cobolt Samba 532-150-200 for sale. This came out of a very expensive flow cytometer with fewer than 860 hours use. Sam tuned up the TEC's and the laser has a custom made solid billet aluminum stand for the head. The laser is set at 175 mW TEM 00 single frequency. The controller and DC supply are mounted on an aluminum plate-plug and lase! No cooling fan is required-no vibration. These lasers are over $13K new and we are asking $4K. See the laser data sheet here; these are very reliable quiet lasers:

We only have one. Phil and Sam
