Tunable laser light source
LS-601A series are the flag ship of the tunable laser light sources Koshin Kogaku Co., Ltd. offers. This product has the high resolution of wavelength and the narrow spectrum linewidth less than 30kHz, and is applicable to the measurement of DWDM optical components and equipments. The low RIN property enables this product to be applied to the evaluation of EDFA.
Features
1.Wide dynamic range
LS-601A series guarantee an accurate measurement of optical devices with its extraordinary wide dynamic range.
2.Low noise
LS-601A sereis is best suitable for noise figure (NF) measurement of the optical fiber amplifier: EDFA, etc. The excellent RIN (Relative Intensity Noise) characteristics ensures accurate measurement without affecting the characteristics of measuring object.
3.Narrow spectrum linewidth
Spectrum linewidth indicates the distribution of wavelength, and the narrower the spectrum line-width, the higher the wavelength isolation. Variation of the oscillation frequency affects the optical spectrum linewidth.
4.Source of light for the beat light
It is the best as the source of light that generates an optical beat because of the light of stable frequency and the high-resolution evaluation wavelength setting.
5.Modulation function
