When selecting acoustic-optic devices for a laser system, a key issue is whether you need to control the light intensity,…
What Causes Q-Switch Pulse Instability?
Unstable laser pulses can lead to inconsistent marking depth, uneven material processing, and reduced production efficiency. In Q-switched laser systems,…
How to Choose Optical Delay Range for an Interferometer?
To select the appropriate optical delay range, three issues need to be considered first: What is the required optical path…
Optical Delay vs. Phase Delay: What Is the Difference?
The optical delay is closely related to the phase delay, but they are not the same. Optical delay indicates the lag…
How to Choose the Right Q-Switch for a Laser?
When choosing the Q-switch of a laser, one should not only consider the wavelength. Even if the wavelengths are the…
How to Measure AOM Diffraction Efficiency?
The diffraction efficiency of an AOM (acousto-optic modulator) is usually evaluated by the ratio of the power of the first-order diffraction light…
How to Build a Fiber-Based True Time Delay System?
The fiber-based true delay system can provide precise optical delay in radio frequency (RF), microwave photonics, optical fiber sensing, and…
How to Select a High-Power Fiber Isolator for MOPA Systems?
When choosing a high-power fiber isolator for the MOPA system, it is not only necessary to consider the rated power…
How to Match an AOM Driver With an RF Amplifier?
When choosing RF devices for an acousto-optic modulator (AOM), it is not only about matching the frequency but also about determining…
How AOMs Control Laser Frequency in Cold Atom Experiments
In cold atom experiments, precise control of laser frequency is crucial for laser cooling, trapping, energy level preparation, and Raman…
AOM Rise Time vs Beam Diameter: Why Smaller Beams Switch Faster
If you need to speed up the switching speed of the acousto-optic modulator (AOM), changing the radio frequency or the driver…
Optical Delay Line Resolution vs Accuracy vs Repeatability
When comparing optical delay lines, you may come across specifications such as a 10 fs resolution, ±10 fs accuracy, and…
