Avesta 固体光纤激光器相关论文
Multidimensional visible spectroscopy using pulse shaping to produce pulses with stable controllable phases and delays has emerged as an elegant tool to acquire electronic spectra faster and with greatly reduced instrumental and data processing errors. Recent migration of this approach using acoustooptic modulator (AOM) pulse shaping to the mid-infrared region has proved useful for acquiring two dimensional infrared (2D IR) vibrational echo spectra. The measurement of spectral diffusion in 2D IR experiments hinges on obtaining accurate 2D line shapes.

In this work we report a new method for controlling the bandwidth of few-cycle optical pulses, using another femtosecond laser pulses chirped in a neonfilled hollow-core fibre. The observed bandwidth varies from 25 to 234 nm in the optical wavelength region 600–950 nm. The pulse energy has for the first time reached a sub-millijoule frontier at 1 kHz. The input pulses are positively chirped using a chirped-pulse amplifier to acquire the widths 32–56 fs at the entrance of the hollow fibre. Then the pulses are highly dispersed due to a self-phase modulation in a nonlinear medium (a neon gas) followed by a pair of chirped mirrors that compensate the dispersion. We have found that this scheme allows for direct tuning of the output-pulse bandwidth while varying the chirping of the input pulses under different neon-gas pressures.

A laser system utilising the method of synchronous pumping of a Ti : sapphire laser by a high-power femtosecond Yb3+- doped laser is described. The pulse repetition rate of the Ti : sapphire laser is successfully locked to the repetition rate of the Yb laser for more than 6 hours without the use of any additional electronics. The measured timing jitter is show to be less than 1 fs. A simple qualitative model addressing the synchronisation mechanism utilising the сross-phase modulation of oscillation and pump pulses within a Ti : sapphire active medium is proposed. Output parameters of the Ti : sapphire laser as functions of its cavity length are discussed in terms of this model.
