Buying Laser Noise Measurement Equipment
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.

![]() 43 Sparta Avenue Newton, NJ 07860 United States | ![]() 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. |
