Buying Laser Noise Measurement Equipment

Top-level product category: detectors and measurements

More specific product categories: intensity noise measurement equipment, phase noise measurement equipment, timing jitter measurement devices

Related product category: laser stabilization devices

Different types of laser noise sometimes need to be assessed quantitatively, such as intensity noise, phase noise, fluctuations of pulse parameters like energy and duration, and timing jitter. The required equipment may include fast photodetectors, electronic spectrum analyzers, optical cross-correlators, and computers with specialized software.

Aspects to Consider Before Buying

Some aspects to consider before buying laser noise measurement equipment: types of measurements (e.g. intensity noise, phase noise), suitability for laser pulses, measurement accuracy, sensitivity, compatibility with lasers, user interface, durability, data recording and processing options, environmental resistance, calibration needs, maintenance, reliability.

For responsible purchase decisions, we recommend applying good practices.

laser noise measurement equipment

Thorlabs manufactures a high-precision intensity noise analyzer for measuring intensity noise in optical systems. Featuring a DC to 3 MHz input frequency bandwidth, this device overlaps data from several sample rates to optimize resolution bandwidth and provide high frequency-axis resolution over its full bandwidth; the 9 Hz minimum resolution bandwidth is ideal for resolving low-frequency noise sources. With a nominal noise floor less than -140 dBV2/Hz, this low-noise instrument is designed to identify environmental noise sources in an optical experiment, such as ambient lighting or electrical line noise. Ideal applications also include light source and instrumentation development, where characterizing noise levels or detection limits is critical.
