Abstract
A power laser has a cavity (2) delimited at its opposite ends by a first partially transmitting window (3) and a second reflecting window ( 4). The first window (3) is constituted by at least one diamond wafer (5) with uncoated flat parallel surfaces, having a controlled thickness whose variations do not exceed 0.2 micron. The diamond wafer (5; 6) is mounted in an annular support (9; 10) of material which is a good heat conductor and is provided with a cooler (11; 12). The window (3) can comprise two parallel wafers (5.sub.A, 5.sub.B) of diamond separated by a calibrated distance (14) which is an uneven multiple of .lambda./4n, .lambda. being the laser wavelength and n the index of refraction of the medium between the wafers. Or the second window (4) can also be constituted by a diamond wafer (6) with a reflective metallic coating (60). A sweeping gas can be blown over the internal surface of at least one of the windows.
