Choosing professional laser equipment is easier when the steps are kept in order. The first step is the application: hair removal, tattoo removal, skin rejuvenation, scar treatment, body slimming, or skin analysis. Each application page on this site shows which models are documented for that application and which families are listed only at category level, and that distinction should shape the shortlist from the start. An application served only by listed families needs a specification request before it can be compared with an application served by documented models.
The second step is to compare documented models on their documented figures. For hair removal, that means the BBT PRO diode system and the Alexandrite plus Nd:YAG system, compared on wavelength, energy, spot size, frequency, and cooling as their detail pages give them. For rejuvenation and resurfacing, it means the diode, picosecond, TwinLaser, and thulium models, compared on the same discipline. The comparison guides on this site are built for exactly this step, and they refuse to invent a comparison point where one side has no documented figure, which is why the CO2 model's parameter gap is stated wherever it arises.
The third step is inquiry confirmation, and it applies to every model, documented or not. Before ordering, confirm the specification sheet for the exact model, the warranty terms for that model, the current minimum order quantity, the current lead time, and the certification documents for your market. Documented figures on this site are a starting point for that conversation, not a substitute for it, because a model revision can change a figure and because a certificate that applies to one market does not automatically apply to another.
Two common mistakes are worth avoiding. The first is transferring a specification from one model to another in the same family, which this site's structure is designed to prevent: every detail page states that its figures belong to the named model only. The second is treating a product name as a specification, which is most tempting with listed families whose names mention wavelengths, temperatures, or uses. A name is a pointer to a question, and the inquiry guide lists the questions that turn a name into a confirmed specification.
If the shortlist still contains a listed family with no documented specification, that is not a reason to drop it, but it is a reason to ask for its specification sheet before comparing it with a documented model. A fair comparison needs both sheets side by side. The inquiry guide explains how to request them, and the contact page provides the form and the published contact details for doing so.
