Compression of Mode-Locked Nd: YAG Pulses to 1.8 Picosecondsde optical fibers and a grating pair dispersive delay line. Although we generated pulses as short as 1.0 picoseconds, pulsewidths of 1.8 picoseconds were more routinely obtained. Our compressor incorporated a novel grazing incidence delay line which greatly reduced the grating separation. We achieveBROTH 发表于 2025-3-25 16:03:53

3 MHz Amplifier for Femtosecond Optical Pulsesh repetition rate amplification is that the energy of the available pump pulses is only a few microjoules as compared to the hundreds of millijoules available for low repetition rate amplifiers . We resolve this problem, in part, by using multiple collinear passes to extract efficiently the pump不能平静 发表于 2025-3-26 01:20:04
Colliding Pulse Femtosecond Lasers and Applications to the Measurement of Optical Parametersaintain the best possible temporal resolution. Hence the need for accurate and sensitive techniques to measure the change in pulse parameters transmitted through (or reflected off) optical samples. We show that the mode locked ring laser is in itself an accurate tool to investigate linear and nonlinnitric-oxide 发表于 2025-3-26 07:27:49
High Power Picosecond Pulses in the Infraredvely mode-locked lasers. At other frequencies, however, this need not be the case. Although not usually explicitly stated, a high power picosecond (or subpicosecond) visible pulse can be used in conjunction with any of a number of nonlinear techniques to generate low power pulses of similiar duratioCabg318 发表于 2025-3-26 12:06:44
Procedure for Calculating Optical Pulse Compression from Fiber-Grating Combinationsinterest to know how much compression is possible and what will be the necessary fiber length and grating separation, given some particular initial optical pulses. This is not immediately obvious, because the achievable pulse compression and the quality of the compressed pulse are sensitive functionCRUC 发表于 2025-3-26 14:03:09
Generation of Infrared Picosecond Pulses Between 1.2 μm and 1.8 μm Using a Traveling Wave Dye Lasermped cw dye laser system tunable around 1.3 μm /2/. Here we demonstrate a new method for effective pumping of dyes with small fluorescence quantum yield (10.). Laser emission up to 1.8 μm is now accessible by a traveling wave pumping system.Regurgitation 发表于 2025-3-26 18:04:47
A New Picosecond Source in the Vibrational Infraredamplified synchronously pumped dye laser operating with rhodamine dyes is reported.. The simplicity and efficiency of SERS as a frequency shifting technique have been amply demonstrated with nanosecond pulses.. SERS has the advantages of using a non-damageable medium and having no phase-matching req
