Abstract :
We propose to operate a Nd:YAG laser at the secondary emission line of 1319 nm and Raman shift in H2 to the first Stokes at 2918 nm near the maximum of water absorption. The quantum efficiency is 45 % and energy conversion of 25 % is achievable in practice. A 300 mJ Nd:YAG laser at 1.32 μm will produce 75 mJ near 2.92 μm and this will be sufficient for corneal sculpting. Such a system has advantages in terms of cost of manufacturing and maintenance compared to excimer lasers
