Where the numbers come from

The Laser Focus World Annual Review and Forecast of the Laser Marketplace is based on a worldwide survey of laser producers and covers 27 types of lasers and 20 applications.

The Laser Focus World Annual Review and Forecast of the Laser Marketplace is based on a worldwide survey of laser producers and covers 27 types of lasers and 20 applications. Diode-laser market information is provided by Strategies Unlimited (Mountain View, CA). Industrial-laser market information is provided by Industrial Laser Solutions, and the Medical Laser Report newsletter provides the medical market analysis. This review is the only major survey of its kind in this industry whose results are made public.

For many, both inside and outside the industry, from private-sector investors to foreign and U.S. government bodies, this report is the only objective summary of major trends in our industry that is readily available. This article, Part II, covers the diode-laser marketplace. Part I, published in January, examined the overall market trends with more detail on nondiode lasers.

Collecting the data

We conducted our research and analysis for the Review and Forecast during October and November 2004. We asked manufacturers to provide a confidential estimate of total worldwide market size (dollars and units) for 2004, based on year-to-date actual data, and a forecast for 2005. In addition to the information provided by the manufacturers, we also used data from other more narrowly focused market surveys, and we incorporated commentary provided by industry analysts who added market insight for specific segments. The detailed fiber laser sales information this year was provided by SLI Optics (Southampton, England), whose help over the past couple of years in getting a handle on the fiber-laser business has been invaluable.

Changes from last year

A comparison of last year’s 2004 estimates with this year’s restated 2004 numbers will show differences and occasional discontinuities in the numbers reported as compared to last year. In general, no attempt has been made to explain these differences in detail. We request “bottom-up” market estimates, and the respondents to our survey do vary from year to year-both in terms of the companies involved and the individuals-so variations in the results are inevitable. In addition, changes in market visibility occur as market shares change. Differences in the overall numbers for 2004 last year and for 2004 this year may also reflect whatever degree of optimism or pessimism was inherent in last year’s forecast (see Optoelectronics Report, February 1, 2004).
