I have been working with my Fotona from year 2000 and with my WMD for less of one year.
Two good laser but different.
Advantages:
Fotona
1) The articulated arm (its optical fiber is not damaged).
2) Their pulses can be varied from very long to very short (ultra short pulse), WMD also.
3) He is hard to break. It doesn’t have tips

WMD:
1) The handpiece are very manuable. with light and super spray.
2) It’s easy to work with the fiber delivery system
3) The tips make the work easy

Disadvantages:
Fotona
1) The articulated arm (Its handling is very difficult).
2) It doesn’t have good spray. I did mine.
3) It’s difficult to move.

WMD:
1) He is more fragile that the Fotona.
2) It’s difficult to arm.
3) Tips is damaged easily.

The Lares Powerlase is also known as the Fotona Fidelis Nd:YAG in Europe, and is one of the most well known sought after units here.

Check out the fotona site at http://www.fotona.si , they are the manufacturers.

I just entered this forum and find the information on the Lares Powerlase AT interesting but very dated.  Does anyone have new comments to update this info?  I am looking seriously at this laser but I want to hear more from those who have experienced it.

Thanks

Jeff: I have noticed a lack of replies on the Powerlase AT in posts here and at Dentaltown.

Is that a sign?

I would definitely ask for references and a full list of them.

I myself would look at other lasers and compare including biolase and Hoyas Versawave which I own.

You decide then which brand has the most appeal for your practice.

Make sure you consider number of existing users, warrantee after the initial year, reliability, training etc.

Good luck in your search.

Thanks, Ron, for your report on these new lasers! Those Zap lasers will appeal to a wider range of dentists who want to enter the laser arena. Did you have a great time in Vegas?
