Diode lasers are by far the most efficient lasers currently available. With the ever‐continuing
improvement in diode laser technology, this type of laser has become increasingly attractive …

Based on enhanced upconversion, we demonstrate a highly efficient method for converting
a full image from one part of the electromagnetic spectrum into a new desired wavelength …

A generic approach for generation of tunable single frequency light is presented. 340 mW of
near diffraction limited, single-frequency, and tunable blue light around 459 nm is generated …

We investigate the possibility of improving the beam quality and obtaining high conversion
efficiency in nonlinear sum-frequency generation. A 765 nm beam from an external cavity …

A computer controlled tunable mid-IR light source, based on single resonant difference
frequency generation (DFG), is experimentally investigated. The DFG process is pumped by …

A new approach for efficient second-harmonic generation using diode lasers is presented.
The experimental setup is based on a tapered amplifier operated in a ring resonator that is …

Sum‐frequency mixing of an 808 nm broad area laser (BAL) with a build‐in grating structure
for spectral control and a 1064 nm solid‐state laser is experimentally investigated. The …

In this paper a generic approach for visible light generation is presented. It is based on sum
frequency generation between a semiconductor disk laser and a solid-state laser, where the …

We present a generic approach for the generation of tunable single-frequency light and
demonstrate generation of more than 300 mW tunable light around 460 nm. One tapered …

Over the last fifteen years, a series of theoretical and experimental investigations have
demonstrated the usefulness of circular geometries to tailor second-order nonlinear optical …
