To continue about National Laser Tech:
I had a real nice guy named Kevin in my office to do the “tune-up” on the laser. Kevin is a former Biolase employee, and my sense is that there are other like him at NLT.
He explained the process, why it needs to be done, and showed me everything. He spent 1.5-2 hours in the office. Filters were inspected & changed, fibers inspected and polished, mirrors inspected and polished, machine calibrated, and much more. The best was the fan noise reduction kit. All WL owners know how loud the machine is, in fact when it is turned off it is somewhat of a relief to the ears. NLT has this fan noise reduction kit for about 400 bucks that reduces noise by approx 80%. IF the noise bothers you , this would be worth the call.
They are also coming out with a software MD upgrade ,for approx &#36500 , which will allow WL users to vary frequency and pulse duration.
I talked about replacement fibers. They sell refurbished fibers for ~&#36500. They claim there is no need to spend &#361800 on a new fiber. Many fibers we get are already refurbished, they claim.
