The combination of Stimulated Raman scattering (SRS) with second harmonic generation (SHG) and sum-frequency generation (SFG) has significantly broadened the range of wavelengths available from solid-state lasers, enabling the production of traditionally hard-to-reach wavelengths in the UV and visible...
High power continuous wave operation of mid-infrared quantum cascade lasers In recent years laser emission from unipolar quantum cascade (QC) structures has been demonstrated in a wide range of wavelengths and temperatures. Continu... A Tredicucci,J Faist,F Capasso,... - Conference Proceedings. ...
The simultaneous emission wavelengths varied from 2 to 5 in the range from 1045.4 to 1063.6nm with the change of the absorbed pump power and crystal length. An output power of 1.4W was obtained with four-wavelength emission, corresponding to an optical鈥搊ptical slope efficiency of 23.7%. ...
16 fabricated multi-quantum-well CS nanowire heterostructures based on well-defined III-nitride materials that enabled lasing over a broad range of wavelengths at RT. Hua et al.17 reported a near-infrared lasing in highly uniform GaAs/GaAsP coaxial CS nanowires, operating at a temperature up to...
Data are presented demonstrating room‐temperature continuous (cw 300 K) photopumped laser operation of AlxGa1−xAs‐GaAs (x∼0.4) quantum well heterostructures (QWH) at wavelengths as short as &lgr;∼7270 A˚, or h&slash;&ohgr;−Eg(GaAs)∼280 meV....

High-temperature continuous-wave operation of optically-pumped type-II W lasers from 36.3 m Summary form only given. The development of semiconductor lasers capable of emitting at wavelengths longer than 3 /spl mu/m at high CW operating temperatur... WW Bewley,CL Felix,I Vurgaftman,... - ...
Asymmetric pulsed fields are applied for continuous-flow operation, which sorts DNA molecules in different directions according to their molecular masses, much as a prism deflects light of different wavelengths at different angles. We demonstrate the robustness of the device by using it to separate ...
One interesting development is a launch is by Foba which has developed a 532 nanometres wavelength green laser marking systems which it says "offers new possibilities" for industrial direct park marking, completing its range of laser wavelengths in its portfolio of marking systems. Foba products ...
Still another object of this invention is to provide a lasing system that operates at short wavelengths. A further object of this invention is to provide a chemically pumped electronic transition laser. Still a further object of this invention is to provide an atomic iodine laser that operates ...
