description | The disclosed device for the laser ablation of materials (and variations) relates to the field of laser technology, and is intended for medical instruments used in stomatology, dermatology, otorhinolaryngology, as well as for instruments used with endoscopes. The invention is a tandem device which increases the coefficient of useful action, pulse energy, and radiation power with a wavelength of 3+/-0.2 mu m. The device comprises an excitation laser (1) with a radiation range of 0.93-1.15 mu m, which is connected by means of a flexible wavebeam guide (3) to a laser converter (2) with a radiation range of 3+/-0.2 mu m. Disclosed are four variations of the device, each being distinguished from the others by the crystal composition of the active element (6) of the laser converter (2), which are multiple-component fluorides of lithium (Li), sodium (Na), barium (Ba), and holmium (Ho), with additions of praseodymium (Pr), ytterbium (Yb), or yttrium (Y).
L'invention concerne un dispositif d'ablation au laser de matériaux (variantes). Cet emprunt à la technique du laser est destiné à des instruments à usage médical utilisés en stomachologie, dermatologie, otorhinologie, et à des instruments conçus pour utiliser des endoscopes. L'invention est un dispositif à couplage permettant d'accroître le coefficient d'action utile, l'énergie des impulsions et la puissance de rayonnement d'une longueur d'onde de 3+/-0,2 mu m. Le dispositif comprend un laser de pompage (1) rayonnant dans une gamme comprise entre 0,93 et 1,15 mu m. Sont également proposées quatre variantes du dispositif, qui se distinguent entre eux par la composition des cristaux de l'élément actif (6) du laser-convertisseur (2), qui sont des fluorures à composants multiples de lithium (Li), sodium (Na), baryum (Ba) et holmium (Ho), avec des adjonctions de praséodyme (Pr), d'ytterbium (Yb) ou d'yttrium (Y). |
