It is well known that innovation is the engine that drives the growth machine of modern capitalist economies. Therefore, not surprisingly, substantial attention has been devoted by economists to the process behind the production of innovations. Three areas have recently emerged as relevant in the field. These are: the impact of spillovers on productivity; the different forms of R&D cooperation and the role of patents in fostering innovations when these are cumulative. In this paper I summarise the relevant literature in these three areas by discussing where the current literature stands and what are its future developments.

Here we present a compact all-room-temperature frequency-doubling scheme generating orange light, using a PPKTP waveguide and a quantum-dot external cavity diode laser (QD-ECDL). The maximum output power for the second harmonic generated light (SHG) was 1.43 mW at 613 nm, achieved for 70 mW of launched pump power at 1226 nm. This represents an important step towards a compact and wall-plug-efficient coherent orange light source, operating at room temperature.
