Abstract. Subject of investigation is a new high-powered strontium bromide (SrBr 2 ) vapor laser emitting in multiline region of wavelengths. The laser is an alternative to the atom strontium lasers and electron free lasers, especially at the line 6.45 m µ which line is used in surgery for medical processing of biological tissues and bones with minimal damage. In this paper the experimental data from measurements of operational and output characteristics of the laser are statistically processed by means of cluster analysis and tree-based regression techniques. The aim is to extract the more important relationships and dependences from the available data which influence the increase of the overall laser efficiency. There are constructed and analyzed a set of cluster models. It is shown by using different cluster methods that the seven investigated operational characteristics (laser tube diameter, length, supplied electrical power, and others) and laser efficiency are combined in 2 clusters. By the built regression tree models using Classification and Regression Trees (CART) technique there are obtained dependences to predict the values of efficiency, and especially the maximum efficiency with over 95% accuracy.

“…Due to its acceptable price, compact size, and easy operation, the strontium laser successfully competes with free electron lasers, generating at the same wavelength. For this reason, the design and development of the strontium laser continues to be of interest [1,8]. The strontium atom actively affects the laser tube -quartz or ceramic -causing its destruction.…”

“…In [4] for the first time a laser based on SrBr 2 excited by a nanosecond pulsed longitudinal discharge was reported. In [5,6] a significantly improved version of this device with laser output power of 2.4 W was presented, and in [7,8] the laser output power reaches 4.27 W, with 90% of the generation at the 6.45 μm line. The obtained results are comparable with those of a metal strontium laser.…”

The subject of investigation is a SrBr 2 laser generating at a wavelength λ = 6.45 µm. This type of laser generation is finding ever wider application in medicine when working with soft and bone tissue providing rapid subsequent recovery. Of all laser sources generating at this wavelength, the new SrBr 2 laser is gaining ever more ground due to its advantages and is therefore of commercial interest. With the goal of developing new, higher-powered SrBr 2 lasers, in this paper, the so-called phenomenological modeling has been used for the first time for this type of laser. An estimation of the degree of influence of 7 independent input laser quantities on laser output power has been performed using factor and regression analysis. A methodology has been developed with the help of which a series of new SrBr 2 lasers with higher output power than existing ones has been predicted. Problems related to the planning of the experiment have been partially solved -carrying out of filtering and extremal experiment.
