Laser technology has considerably expanded therapeutic modalities in dermatology and aesthetic medicine. In addition, lasers have broadened the spectrum of diagnostic and therapeutic options in many other medical fields. Dermatologists, especially Dr. Leon Goldman, played an important role in the evolution and use of medical lasers. There was a long way from the concept of stimulated emission as the fundamental idea of laser technology by Albert Einstein in 1917 to the practical use of the laser today. We review the development of laser technology from the early days through the latest advances.

“…Second‐order nonlinear optical effects such as second‐harmonic generation (SHG), parametric down‐conversion, and difference‐frequency generation have generated remarkable progress in applications and fields such as ultrafast optical spectroscopy, [ 1 ] harmonic generation microscopy, [ 2 ] and quantum computing. [ 3 ] Frequency‐doubled lasers, [ 4 ] optical parametric oscillators, [ 6 ] and amplifiers [ 8 ] and terahertz radiation sources [ 9 ] are all examples of useful devices that rely on second‐order nonlinear effects. Moreover, apart from χ (2) based light generation, electro‐optic modulators [ 10 ] based on the Pockels effect are key devices used in our communication world.…”

Second-order nonlinear optical processes enable a wide range of applications used in research and industry. The majority of available second-order nonlinear devices however relies on bulk nonlinear crystals with low second-order nonlinearity. By exploiting the advancements made in integrated optics, materials with large second-order nonlinearity could enable efficient and small-sized on-chip nonlinear devices at low cost. Unfortunately, silicon and silicon nitride, mostly used for photonics integrated circuits exhibit negligible second-order nonlinearity (χ (2) )and alternate materials have to be investigated. PZT thin films with high second-order nonlinearity stand as a good candidate for on-chip nonlinearity. We demonstrate here an electric-field induced tuning of χ (2) in PZT thin films grown on glass substrates with a tuning efficiency of 3.35 pmV -2 . We record strong second-harmonic generation and report a very high dominant tensor component ( ) of 128 pmV -1 . The χ (2) of our PZT thin films can be reversed by poling with a DC electric field at room temperature. This opens avenues for highly efficient and tunable on-chip nonlinear devices.
