Well, I realized I didn’t even post to my own post….

Both the Pulsemaster and the PerioLase are free-running pulsed Nd:YAG solid-state lasers and were designed by the same designer and engineer, Mike Yessik and Rick Thompson.  ADT purchased the rights to the Pulsemaster in 1994 when their OEM deal with Sunrise went sour, while Millennium Dental Technologies (a company I co-founded with Dr. Del McCarthy) worked with Rick and Mike in January of 2000 to design from scratch a pulsed Nd:YAG laser with 21st Century technologies and to our specifications and our input to the clinical needs of end-users–novice and expert alike.  As an aside–We formed MDT when we couldn’t get manufacturers interested enough in our findings regarding the importance of pulse duration or lasers for their importance in periodontal therapy (not hygiene curettage)–hence the name we coined “PerioLase” cuz no one else was obcessed about lasers for perio like we were.

Del and I realized in 1993-94 that another parameter beside wavelength, power and repetition rate was necessary to control bleeding without charring and the delayed healing that goes with it.  Varying the pulse duration to be “longer” than 100-150 usecs was the answer.  But long pulse is not good for hard tissue (selective caries removal, dentin etching, calcified canal opening, etc) like 100 usecs is……

It’s the same with erbium.  We realized when using experimental erbiums in beginning in 1990-1997 (Kavo in Germany, then P-Optics in California) that another parameter besides wavelength, power, and repetition rate (Hz) was needed for RAPID and SMOOTH cutting of crown preps without injury to the pulp (the electro-mallet effect for those who did gold foils).

You could accurately say that the PerioLase is the next generation of the Pulsemaster having been prototyped by the same designer and engineer….so we must think very highly of the Pulsemaster!
