Tunable laser light source LS-601A series (High-end model)

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.

Specifications

* Specifications are subject to change without notice.

Features

■Wide dynamic range

LS-601A series guarantee an accurate measurement of optical devices with its extraordinary wide dynamic range.

■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.

■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.

* As for our tunable laser light source, a band pass filter is used in an optical wavelength variable mechanism, and it has capabilities of creating a high-level narrow optical spectrum linewidth with excellent monochromatic and the high stability level over a short period of time.

■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.

■Modulation function

LS-601A series has the external high frequency modulation function and the internal low frequency modulation function.  These functions enable a more accurate mearsument of an optical characteristic,

Applications

■Mearsurement of the optical components and equipments

Our tunable laser has GP-IB, and it measures coordination between PC and Power Meter.
You can use other measuring instruments with synchronization by the external output trigger.

■Fiber sensing

Our tunable laser is the best for fiber sensing, because it has low noise, narrow line-width and high stability.
