High-repetition-rate Cr:Nd:GSGG active-mirror amplifier
Optics Letters, 1987We have designed, constructed, and operated a 3.8-cm clear-aperture Cr:Nd:GSGG active-mirror amplifier. We believe this to be the first active mirror that uses a crystalline host and the largest-aperture Cr:Nd:GSGG amplifier yet reported. We have measured a small-signal gain of 1.6. The wave front has been measured and found to be less than three waves

High-Repetition Rate Broadband Pump–Probe Microscopy
The Journal of Physical Chemistry A, 2019Pump-probe microscopy has recently emerged as an important tool for characterizing the effects of nanoscale chemical and compositional heterogeneity on the optoelectronic properties of material systems. This article describes the development of broadband pump-probe microscopy, which utilizes a high-speed line camera and high repetition rate amplified ...

High-repetition-rate short-pulse gas discharge
Review of Scientific Instruments, 1979A high-average-power short-pulse gas discharge is described. This consists of a volume-preionized transverse discharge of the type used in gas lasers driven by a Blumlein energy storage circuit. The Blumlein circuit is fabricated from coaxial cable, is pulse-charged from a high-repetition-rate Marx-bank generator, and is switched by a high-repetition ...

High Repetition Rate High Power Excimer Lasers
SPIE Proceedings, 1989We report on the development of high repetition rate, high average power excimer laser systems with projected repetition rates of several kHz and multi kilowatt outputs. An optimized system concept has been derived by theoretically and experimentally comparing the various system options.

High harmonic generation at high repetition rates
CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005., 2006We demonstrate high order harmonic generation directly from a 110 MHz femtosecond oscillator using a build-up cavity. This is an important step towards high precision spectroscopy and high power laser sources in the XUV.

High repetition rate LC oscillator
IEEE Transactions on Electron Devices, 1979LC oscillators have been built which can produce multikilowatt RF pulses in the megahertz frequency range with repetition rates of tens of kilohertz. The L and C for these oscillators can be determined from the frequency requirement and the high-Q requirements.

High-repetition-rate high-power femtosecond ArF laser source
Optics Letters, 1994170-fs, 0.8-microJ optical pulses at 193 nm generated by frequency quadrupling of high-power Ti:sapphire laser pulses are amplified in an ArF gain module. Double-pass amplification at a 400-Hz repetition rate resulted in 290-mW average power with pulse durations of ~ 300 fs.

High-repetition-rate high-power variable-bandwidth dye laser
Applied Optics, 1985An efficient high-repetition-rate dye laser is described which has a bandwidth that can be tailored to match typical atomic inhomogeneous linewidths. The dye laser is pumped by a 4-kHz 2–6-mJ/pulse copper vapor laser. The total efficiency of the dye laser (oscillator and amplifier) is 45% for rhodamine 6G and 30% for rhodamine B.

High-repetition-rate diode-pumped Nd:YVO_4 slab laser
Optics Letters, 1994Q-switched pulse energies of approximately 1 mJ at repetition rates as high as 1 kHz have been obtained from an electro-optically Q-switched Nd:YVO4 slab oscillator that was side pumped by a five-bar diode-laser stack. High gain within the slab resulted in pulse durations of less than 5 ns and sub-15-ns buildup times.

High-repetition-rate continuously pumped ruby laser
IEEE Journal of Quantum Electronics, 1971The first successful operation of a high-repetition-rate repetitively Q -switched ruby laser is reported. Using an acousto-optic Q switch, repetition rates up to 5000 pps have been achieved. When the laser is optimized, peak power outputs of 20 kW at 500 pps and 8 kW at 2000 pps can be expected.
