NEWPORT 505B Laser Diode Driver

The Newport 505B is a low noise and highly stable laser diode driver for spectroscopy and fiber-optic communications applications. Two current ranges can be selected from the front panel: 0 to 200 and 0 to 500 mA with a current resolution of 0.004 and 0.01 respectively. Output accuracy on both settings is +/- 0.05% FS. The output compliance voltage can ranges 0 to 7.0 V. The short-term (1 hr) stability on both settings is <10 ppm FS, and long-term stability (24 hr) on both settings is <50 ppm FS. On the 0 to 200 mA output setting, the output noise in high BW mode is less than 1 micro-amp rms. On the 0 to 500 mA setting, output noise is at less than 1.5 micro-amps rms in high BW mode. Output noise in low bandwidth mode from 0 to 200 mA is at less than 0.4 micro-amps rms, and less than 1.1 micro-amps rms on the 0 to 500 mA setting. The current limit range for both output settings is 0 to full range plus 1% of full output, with a resolution of 0.004 and 0.01 mA on the 0 to 200 and the 0 to 500 mA setting respectively. External analog modulation allows for voltage control or modulation of the output. With an input voltage range of -10 to +10 V at 10 k-ohms, in high bandwidth mode, the modulation bandwidth on the 0 to 200 and 0 to 500 mA settings is DC to 660 kHz and DC to 500 kHz respectively. In low bandwidth mode, the external modulation bandwidth is DC to 12 kHz for both output settings. The photodiode input current monitor range is 0 to 5 mA, with a stability of +/- 0.02 mA per hour and an accuracy of +/- 0.05% FS. The bias voltage range is 0 to -5 V. The measurement display current range is identical to the current ranges on both output current settings. The display output current resolution is 0.1 mA on both output settings. The display can show the photodiode current in a range from 0 to 5000 mirco-amps with a resolution of 1.0 micro-amps. The user interface software and drivers are compatible with windows xp and 7, 32 and 64 bit. This model also comes equiped with a usb 2.0 interface for remote operation.

*This is a Web introductory price for one calibration of the NEWPORT 505B. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Coherence Length
Average distance over which superimposed waves lose their phase relationships

Linewidth
Linewidth is the width of a spectral line in terms of wavelength, wave number and frequency.

Power Flatness Versus Wavelength
When changing the wavelength at constant power setting and recording the differences between actual and displayed power levels, the power flatness is ± half the span (in dB) between the maximum and the minimum of the measured power levels.

Spectral Width
Spectral Width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical communications applications, the usual method of specifying spectral width is the full width at half maximum. This is the same convention used in bandwidth, defined as the frequency range where power drops by less than half (at most -3 dB).

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
