TiF-50型 钛:蓝宝石飞秒激光器
产品介绍:
TiF-50型激光器提供了一个兼顾的方案:在较宽的调谐范围内,满足脉宽小于50 fs。
该型激光器是一种灵活的工具,可用于多种应用。该系统可以提供两种基本配置:TiF-50独立版本,使用外部泵浦激光器进行泵浦;或TiF-50F,该系统可在原厂或现场集成一个工业标准泵浦激光器。对以上两个版本的系统中,Ti:S激光头的尺寸都是相同的。独立版可以配备集成泵浦源从而有效降低额外成本。对于TiF-50和TiF-50F激光系统,泵浦功率可高达10W。输出功率和波长的关系可以参考调谐曲线。
该激光系统还可配备双折射滤光器(可选)和标准具(可选),在CW运转条件下,在整个调谐范围内满足窄带可调谐。外置棱镜对或可调谐脉冲压缩器(APC)可以进行色散预补偿。

型号:TiF-100 5万Spectrally correlated photon pairs can be used to improve the performance of long-range fiber-based quantum communication protocols. We present a source based on spontaneous parametric downconversion, which allows one to control spectral correlations within the entangled photon pair without spectral filtering by changing the pump-pulse duration or the characteristics of the coupled spatial modes. The spectral correlations and polarization entanglement are characterized. We find that the generated photon pairs can feature both positive spectral correlations,decorrelation, or negative correlations at the same time as polarization entanglement with a high fidelity of 0.97 (no background subtraction) with the expected Bell state.
We have achieved experimentally a generation of white-light few-cycle femtosecond laser pulses, using a neon-filled hollow-core fibre. The pulses observed by us are as short as 6.22 fs at the repetition rate of 1 kHz, when the input is characterized by the parameters 2.5 mJ and 33 fs. Pulse compression has been achieved using a supercontinuum produced in a static neon-filled hollow fibre, while a pair of chirped mirrors have compensated the dispersion. Our technique allows for directly tuning the pulse duration via changing the gas pressure, while maintaining near-transform-limited pulses with constant output energies and thus reducing the complications introduced by the chirped pulses. Using the measurements of the optical transmission of the fibre as a function of the gas pressure, we have testified a high enough throughput exceeding 60%. This demonstrates the successful compression that yields few-cycle femtosecond-long pulses, with a wide spectral bandwidth.
We investigated Terahertz generation in organic crystals DSTMS, DAST and OH1 directly pumped by a Cr:forsterite laser at central wavelength of 1.25 μm. This pump laser technology provides a laser-toTHz energy conversion efficiency higher than 3 percent. Phase-matching is demonstrated over a broad 0.1-8 THz frequency range. In our simple setup. we achieved hundred μJ pulses in tight focus resulting in electric and magnetic field larger than 10 MV/cm and 3 Tesla.
