High-average-power operation of flashlamp-pumped titanium-doped sapphire
Conference on Lasers and Electro-Optics, 1986At CLEO ’85 we reported an efficient flashlamp-pumped titanium-doped sapphire laser capable of output energies of several hundred millijoules. Despite advances in efficiency, however, high-power operation of the laser was still limited in part by short flashlamp life (~103 shots).

Diode-pumped Yb:LiYF4 chirped-pulse regenerative amplifier for high average power operation
Advanced Solid-State Photonics, 2004A 10 mJ output power was obtained by using a diode-pumped chirped-pulse regenerative amplifier with a liquid-nitrogen cooled Yb:LiYF4 crystal. The pump duration as short as 1 ms would enable 1 kHz repetition rate with a continuous wave pump. The pulse duration compressed in time by parallel grating pair was about 800 fs with 6 mJ output power.

10mJ Hollow-Core Fiber operation at 250W average power with 90% efficiency
Conference on Lasers and Electro-Optics, 2022We developed a high transmission Hollow-core fiber (HCF) with 1mm ID that supports 97% absolute transmission. We were able to achieve about 30 times spectral broadening of 11mJ, 1.5ps pulses from a 275W, 25 kHz InnoSlab multi-pass amplifier with 90% fiber transmission. The spectrum achieved with Kr at 1 bar supports a 50fs TL bandwidth.

Hesitant fuzzy set, as an extension of fuzzy set, has absorbed many researchers from various scientific backgrounds to deal with uncertainty. Solving decision-making problems is one of the most important applications of hesitant fuzzy set. To do so, it is needed to rank hesitant fuzzy elements (HFEs) and to define some mathematical operations on them ...

High-average-power operation of a Q-switched diode-pumped holmium laser
Optics Letters, 1993We have investigated high-peak- and high-average-power operation of diode-pumped, thulium-sensitized, holmium 2.1-microm lasers. Free-running laser powers of 14 W at 29 Hz have been demonstrated with 2.6% electrical efficiency. Q-switched operation produced average powers in excess of 11 W in a burst of short pulses.

Anode Materials for High-Average-Power Operation in Vacuum at Gigawatt Instantaneous Power Levels
IEEE Transactions on Electron Devices, 2015The thermal behavior of several electrically conducting solids under high incident electron fluence in high vacuum was evaluated. At electron energies of up to $\sim 200$ keV, the depth-dose relationship for electron penetration into the materials was considered, and the resulting energy deposition profile from the surface was revealed to extend ...

High average power large-pitch fiber amplifier with robust single-mode operation
Optics Letters, 2011Ytterbium-doped large-pitch fibers with very large mode areas are investigated in a high-power fiber amplifier configuration. An average output power of 294 W is demonstrated, while maintaining robust single-mode operation with a mode field diameter of 62 μm.

Thermal effects of the operation of high average power Gunn devices
IEEE Transactions on Electron Devices, 1970A lumped thermal resistance model is described for GaAs Gunn and LSA diodes. Thermal resistances are defined for the active layer, contact layer, bond interface, package and heat sink. This permits the calculation of tha maximum device temperature T M = T 0 + P Σ i R i and the critical temperature difference across the active layer ΔT A = PR A .
