The MOGLabs Laser Wavemeter is a precision compact laser wavelength measurement device, and optical spectrum analyser, with on-unit display and ethernet/USB connectivity standard. Use it standalone or with the included Windows GUI software package. Unlike interferometric wavemeters, our device clearly reveals multimode laser operation,making it particularly suitable for use with external cavity diode lasers and atom cooling and trapping experiments. Features Picometre (<GHz) accuracy Picowatt sensitivity Any wavelength from 370nm to 1120nm† Instantly identifies multimode input Fast: up to 1250 measurements per second CW or pulsed laser input Built-in PID feedback with analogue output Ethernet and USB standard Applications Laser frequency diagnosis and testing Identifying laser multimode behaviour Determining absorption lines Gas spectrometry Raman fluorescence Specifications MWM Wavelength/frequency Wavelength range 370nm–1120nm Supplied calibrated at one wavelength e.g. 780±12 nm Input power requirement 1 pW (1 picowatt) Precision 100MHz(0.1pm) at 780nm Accuracy ±1 GHz / ±0.001nm at 780nm,at time of calibration Optical resolution <0.02 nm (σ std dev,wavelength dependent) Dynamic range >35dB (>50dB with HDR) Electronics Display Built-in LCD and host computer Interface Windows GUI PID feedback 12-bit DAC output,0.5mV resolution,10 Hz bandwidth Readout Typically 20 per second,up to 100 /s,host dependent Interface Ethernet 10/100 TP RJ45 USB USB2.0,plug type USB-B(350mA with display on) SMA Analogue output,±2.5 V,for PID feedback control Inputs/outputs Optical input FC single mode fibre DAC 12-bit output, ±2.5 V, 0.5mV resolution Dimensions Dimensions (approx.) 165mm x 85mm x 70mm (LxWxH) †Note: the MWM operates over a small wavelength range, e.g. 780 ± 12 nm. Operation in a different wavelength range requires mechanical adjustment and recalibration.
