The Advantages and Disadvantages of Passive vs Active Q-Switching

Q-switching is the most effective method for producing high energy pulsed lasers.  While there are many different varieties of a q-switch, they all follow the same basic operating principle.  Q-switches temporarily increase the cavity losses so that the gain threshold is artificially high preventing the laser from emitting light.  This process allows the population inversion inside of the gain medium to grow until it becomes fully sa… Read More

Laser Diode Fundamentals: What are Longitudinal Modes?

Laser diodes must meet two critical requirements to facilitate the lasing process. The first requires that, at a minimum, the laser cavity’s gain increases to the point that it reaches unity with the level of losses. This unity state is known as the gain threshold. The second requirement is that there must be a longitudinal mode present inside the optical cavity, coinciding with the laser’s gain curve. This article explores precisely what longitudinal modes are and how they affect the laser diode’s pe… Read More

Peak Power and Average Power in ns and Sub-ns Lasers

A significant and well-recognized difference between lasers and conventional, incoherent light sources, is the ability to concentrate laser emission in short pulses, with durations going down to a few femtoseconds, containing potentially only a few optical cycles. Technically, you can drive an incoherent LED source using current pulses. However, each pulse would have a maximum power (i.e. a peak power) equal to the average power of the same device if a continuous bias were applied. Only laser cavities can concentrate the stored energy within active materials in such a way to achieve peak powers orders of magnitude higher than their ave… Read More

What is Single Longitudinal Mode

Within the laser community, one of the most overused and often miscommunicated terms is the phrase “single mode.”  This is because a laser beam when traveling through air takes up a three-dimensional volume in space similar to that of a cylinder; and just as with a cylinder, a laser beam can be divided into independent coordinates each with their own mode structure.  For a cylinder we would call these the length and the cross-section, but as shown in the figure below for a laser beam, we define these as the transverse electromagnetic (TEM) plane and the longitud… Read More
