Continuous-wave optical parametric oscillators and frequency conversion sources from the ultraviolet to the mid-infrared
Devi, Kavita (Universitat Politècnica de Catalunya, 2013-10-24)
Doctoral thesis
Open AccessHigh-power, continuous-wave (cw) optical parametric oscillators (OPOs), from the ultraviolet (UV) and visible to the near- and mid-infrared (IR) wavelength range, are of interest for a variety of applications such as ... -
Continuous-wave, multimilliwatt, mid-infrared source tunable across 6.4–7.5 μm based on orientation-patterned GaAs
Devi, Kavita; Schunemann, P. G.; Ebrahim-Zadeh, Majid (OSA, 2014-12-01)
Article
Open AccessWe report a continuous-wave (cw) source of tunable mid-infrared radiation providing tens of milliwatt of output power in the 6460–7517 nm spectral range. The source is based on difference-frequency generation (DFG) in ... -
Continuous-wave, single-pass, single-frequency second-harmonic-generation at 266 nm based on birefringent-multicrystal scheme
Devi, Kavita; Parsa, S.; Ebrahim-Zadeh, Majid (OSA, 2016-04-18)
Article
Open AccessWe report the implementation of a compact cascaded multicrystal scheme based on birefringent crystals in critical phase-matching, for the generation of continuous-wave (cw) radiation in the deep ultraviolet (UV). The ... -
Fiber-laser-based, high-repetition-rate, picosecond ultraviolet source tunable across 329-348 nm
Devi, Kavita; Kumar, Suddapalli Chaitanya; Ebrahim-Zadeh, Majid (OSA, 2016-10-15)
Article
Open AccessWe report a compact, fiber-laser-based, high-repetition-rate picosecond source for the ultraviolet (UV), providing multi-tens of milliwatt of average power across 329-348 nm. The source is based on internal sum-frequency ... -
Multimilliwatt, tunable, continuous‐wave, mid‐infrared generation across 4.6‐4.7 m based on orientation‐patterned gallium phosphide
Devi, Kavita; Padhye, A.; Schunemann, P. G.; Ebrahim-Zadeh, Majid (OSA, 2018-05-06)
Article
Open AccessWe report the generation of tunable continuous-wave (cw) mid-infrared (mid-IR) radiation across 4608–4694 nm using the new nonlinear material, orientation-patterned gallium phosphide (OP-GaP). By exploiting difference-frequency ... -
Nanosecond difference-frequency-generation in orientation-patterned gallium phosphide
Wei, Junxiong; Chaitanya Kumar, S.; Ye, Hanyu; Devi, Kavita; Schunemann, Peter G.; Ebrahim-Zadeh, Majid (OSA, 2017-05-31)
Article
Open AccessWe report a tunable, single-pass, pulsed nanosecond difference-frequency generation (DFG) source based on the new semiconductor nonlinear material, orientation-patterned gallium phosphide (OP-GaP). The DFG source is realized ... -

Devi, Kavita; Kumar, S. Chaitanya; Ebrahim-Zadeh, Majid (IEEE, 2015-03-05)
Article
Open AccessWe report phase-modulation mode-locking of a continuous-wave (cw) singlyresonant optical parametric oscillator (OPO) in the near- and mid-infrared based on MgO-doped periodically poled LiNbO3 (MgO:PPLN) and pumped by an ... -
Room-temperature, rapidly tunable, green-pumped continuous-wave optical parametric oscillator
Devi, Kavita; Ebrahim-Zadeh, Majid (OSA, 2017-06-29)
Open AccessWe report the first realization of a stable, room-temperature, green-pumped cw OPO using fan-out-grating MgO:sPPLT, providing rapid, continuous and wide-tuning across 734-1929nm, 2.2W of output-power, frequency-stability ... -
Ultrafast optical vortex beam generation in the ultraviolet
Apurv Chaitanya, N.; Chaitanya Kumar, S.; Devi, Kavita; Samanta, G. K.; Ebrahim-Zadeh, Majid (OSA, 2016-06-01)
Article
