The use of furazolidone in food-producing animals is banned within the EU. Detection of the protein-bound side-chain metabolite, 3-amino-2-oxazolidinone (AOZ), in animal tissues is the most effective method of enforcing the ban. The study was underta

The techniques of coupled-cavity modelocking and self-modelocking in which intensity-induced nonlinear effects are exploited have been reviewed for broad-band gain media. Particular emphases have been placed upon the archetypical colour-centre and ti

The pulses from two self-modelocked titanium:sapphire lasers have been time synchronised by locking their repetition frequencies to an electronic crystal oscillator and a relative timing jitter between the lasers of 1–2 ps has been recorded. Somewh

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

An all-solid-state self-mode-locked Ti:sapphire laser is described. This laser was pumped by a diode-laser-pumped intracavity-frequency-doubled cw Nd:YLF minilaser and produced femtosecond pulses for pump powers as low as 500 mW.

A self-mode-locked Ti:sapphire laser system has been constructed that simultaneously generates sequences of femtosecond pulses at two independent wavelength regions. This dual-wavelength, self-mode-locked operation has been shown to exhibit a high de

The self-mode-locking of a Cr:LiSrAl6 laser has been demonstrated. With a pump power of 2 W from an argon-ion laser operating on the 476-nm line, 50-fs pulses were produced in the 800–920-nm tuning range at average powers of ∼150 mW. Although the

We describe the operation of a high average power, high‐repetition rate, femtosecond optical parametric oscillator in the important 3–5 μm spectral region. The Ti:sapphire pumped optical parametric oscillator was based on the nonlinear material

The decay time of the blue luminescence at room temperature in n‐type ZnSe grown by metalorganic chemical vapor deposition has been measured, using a mode‐locked laser as excitation source and a streak camera for detection. Over an uncompensated
