Abstract
The larger DREV project regarding SAR operations includes the combination of far-infrared retroreflectors supplied to personnel and equipments at high risk together with a CO2 laser source as scene illuminator. To be of any use to SAR forces, the laser needs to be powerful (tens of watts) and as compact as possible. A suitable laser candidate, called the Mini-Slab laser, has been developed recently by Boreal Laser. It consists in a RF driven, slab waveguide CO2 laser supposedly capable of output power in excess of 40 watts from a very compact cylindrical volume of 6cm in diameter by 25cm in length. The associated 600W RF power supply, about the size of a litre of milk (8x8x30cm cubic), has also been developed by Boreal Laser. However, once acquired by DREV, the Mini-Slab laser failed to meet its specifications. INO was then mandated by DREV - in an amendment to the contract W7701-5-3183/011/XSK on the development of flexible retroreflectors for the far-infrared - to complete, on a best effort basis, the development of the Mini-Slab laser and to bring it as close as possible to its full specifications. The work, detailed in the following sections, was meant to include the sealing of the laser tube, alignment of the resonator optics, management of the thermal dissipation and verification of the power supply. We will see that much more was and is still needed to achieve Boreal Laser's specifications. TRUNCATED
