Blooming and Smearing in Your Beam Profile? Why It Happens and How to Fix It

When measuring your laser beam profile, you expect the measurement to be accurate, so it can be frustrating to see artifacts that are clearly not right. Before discussing how to fix it, or even when and why it happens, let’s explain what exactly bloom and smear are. What do blooming and smearing look like? Bloom…

Understanding the Specs: Power Meter Damage Threshold

When choosing and using a power meter to measure your laser, one of the most critical specifications to understand is the sensor’s damage threshold. As defined by Ophir, this is the point at which the reading is altered by at least 1% from its original performance (although there may be no noticeable damage). There are…

How to Use LabVIEW to Automate Measurement of High Frequency VCSEL

When measuring high frequency sources, one usually must decide whether they need to know the average power or the temporal pulse shape. Use a precision photodiode to measure average power, but a very fast photodiode must be used for pulse shape characterization. Ophir’s IS1.5-VIS-FPD800 sensor integrates both types of photodiode so you can measure average…
