“…For narrow band (Δλ < 1nm), highly multimode pump light this results in an absorption length of 0.25 cm, however for a typical diode laser spectrum of 3 nm FWHM the absorption length increases to ~0.5 cm. The waveguide films were grown onto a <100>oriented YAG substrate of dimensions 10 x 10 x 1 mm using the setup described in [12][13][14].…”

Fabrication, characterization and laser performance of a Watt-level ytterbium-doped yttria waveguide laser is presented. The waveguide was grown onto a YAG substrate by pulsed laser deposition and features a 6 µm thick ytterbium-doped yttria layer sandwiched between two 3 µm undoped yttria layers. The laser deposited film was characterized by X-ray diffraction, showing a high degree of crystallinity and analyzed spectroscopically, showing performance indistinguishable from previously reported bulk material. When pumped with 8.5 W from a broad area diode laser the waveguide laser produces 1.2 W of output at 1030 nm.

“…We have achieved some success in growing mm-sized crystal features through a 25 µm silicon mask attached to the substrate via solvent capillary action, in which methanol bonding [41] was chosen as the method of applying the mask to the substrate. The single-crystal YAG substrate was cleaned, placed in a dish and covered in methanol.…”

“…An alternative approach, which proved to be experimentally easier, involved multi-plume cone growth as illustrated in figure 19, whereby one plume is funnelled through Figure 19. Schematic of multi-plume growth using a combination of plume funnelling and a separate plume outside the cone to produce a horizontal (in-plane) grading of composition (after Sloyan et al [41]). .…”

We discuss our progress in the use of multiple laser beams and multiple targets for the pulsed laser deposition of thin films for waveguide laser and magneto-optic applications. In contrast to the more widely used single-beam/single-target geometries, having more than one laser-produced plume can allow tuning of the material properties and complex engineering of the deposited thin films. For optical applications-the majority of the work reported here-dopants can be selectively introduced, lattice mismatch and residual strain can be compensated, which is an important factor for successful growth of thin films of ∼ tens of microns thickness, and refractive index values can be adjusted for fabrication of sophisticated waveguiding structures. We discuss mixed, layered, superlattice and Bragg reflector growth, which involve out-of-plane engineering of the film structure, and in-plane engineered geometries for designs relevant to thin-film disc lasing devices. Finally we briefly discuss our most recent use of multi-plume growth for magneto-optic thin films, which involves compositional tuning of final magnetic properties.
