Hi guys,

Does anybody have anything to say about Yongli tubes?

I am considering their DLT-280 or DLT -300 tubes which is just two separate glass tubes combined design inside a metal case. It is exactly two separate tube design not a single folded U shaped glass tube like ERF -220.

If you do not have DLT-280 or DLT -300 I am happy with any opinion on their regular glass tubes. I do not think their are using somebody else's tubes in their DLT series.

This DLT tube will go as a replacement for my two GSI 140W tubes that are combined with a Brewster window in my laser. If Yongli tube is good I will just remove my GSI tubes and a Brewster window and I will use a single DLT-280/300 instead to direct the beam to my laser head.

I may be even able to use my original HVPSs that are powering my GSI tubes. However I will get Yonli power supplies with a DLT tube so if mine do not work I will just swap power supplies.
