Laser Noise Analyzer (GP-LWM100)
GP-LWM100 is a sub-Hz-level noise linewidth test and analysis instrument independently developed by Xunsu Xinyuan. It adopts self-heterodyne coherent phase noise extraction technology and noise state estimation technology, achieving ultra-low noise floor laser noise testing, and providing a testing method for lasers with intrinsic linewidth below Hz.; The GP-LWM100 laser ultra-narrow linewidth/phase noise analyzer can quickly measure the phase noise of a laser and estimate its FWHM linewidth down to <1Hz, without the need for complex configuration or a reference laser. This system, based on self-heterodyne coherent phase noise detection technology, is unique in the field of broadband measurement and requires no additional low-noise reference laser source or spectrum analyzer. GP-LWM100 can easily achieve precise operation through a dedicated graphical user interface, running efficiently and responding quickly. Without any additional test equipment, its unparalleled ultra-low phase/frequency noise analyzer supports multi-input wavelength band expansion and optionally provides low relative intensity noise (RIN) measurement functionality.
