Pulses having durations as short as 60 fsec have been directly generated by a self-mode-locked, dispersion-compensated Ti:sapphire laser. By using an extracavity fiber-prism pulse compressor, pulse durations as short as 45 fsec have been obtained.
Four different techniques for the extraction of veterinary drugs were compared. The use of a high speed mixer/emulsifier, an ultrasonic bath, a Stomacher and an end-over-end mixer were used to extract both incurred and fortified residues of chlortetracycline, sulphadiazine and flumequine from chicken muscle. For each drug, similar analytical recoveries from… (More)
It is demonstrated that the incorporation of an acousto-optic modulator within the cavity of a self-mode-locked Ti:sapphire laser can lead to self-starting and stable generation of pulses that have durations of 60 fs when the acousto-optic device is driven regeneratively from the laser output. Data are also presented that show that the application of… (More)
Title of Thesis: INTERCALATED MoS2 NANOPARTICLES FOR ENHANCED DISPERSION IN SMOKES AND OBSCURANTS D’Anne Emmett Spence, Master of Science, 2003 Thesis Directed by: Professor Bryan W. Eichhorn Department of Chemistry and Biochemistry The intercalation of MoS2 with diethyl oxalate (DEO) and Meldrum’s Acid (MA) has been achieved via an exfoliation and… (More)
The experimentally measured timing jitter of a self-mode-locked Ti:sapphire laser is compared with the theoretically predicted quantum limit. Timing jitter figures of 150 fs (100-500 Hz) and 80 fs (500-5000 Hz), which approach the quantum limit, have been achieved by use of an improved cavity phase-locking technique.
A Ti:sapphire-pumped, high-repetition-rate, femtosecond optical parametric oscillator based on potassium niobate is described. Signal pulses as short as 90 fs have been recorded, and idler pulses as short as 105 fs have been measured. Tuning from 1.2 to 1.4 microm in the signal branch and from 1.76 to 2.2 microm in the idler branch has been achieved. Output… (More)
