A perhaps not very practical, but theoretically very interesting high-power laser concept is that of the radiation-balanced laser. Here, the heat generation in the gain medium is essentially eliminated by optical refrigeration. The power conversion efficiency, however, is quite low.

201586 — The Fourier transform of the Airy intensity pattern is the autocorrelation of the aperture disks, same as convoltion in this case I believe.

An important safety principle in the area of high-power lasers is to enclose the laser setup with a solid housing, and ideally also the whole area where dangerous laser beams can be present. Interlocks can prevent the operation of a laser at times where persons are in a hazardous area.

Ultraviolet Cold Mirrors are slightly different than the standard Cold Mirror whereas they efficiently reflect the ultraviolet and transmit the visible and infrared. They are normally used at an angle of 45° and are excellent for applications where one wants to separate the ultraviolet from the visible and near infrared.

An aspect of great importance for further laser development is that of power scaling, based on certain power-scalable laser architectures. Even for not power-scalable laser types, it can be very helpful to understand the scaling properties of various parts or techniques.

Most models for 808 nm, 915 nm, 976 nm or 1064 nm are available as stock items or assembled with a turn-key high-power laser diode driver with air-cooled temperature regulation. Versions with a high-power optical fiber connector or with a 3-mm output collimator are available.

CNI high power lasers include both DPSS lasers and diode lasers. They are widely used in medical, scientific research, material processing and industrial applications. Available wavelengths are include 532 nm, 556 nm, 589 nm, 660 nm, 808 nm, 880 nm, 980 nm, 1064 nm, 1319 nm and others. The average output power of 532-nm green lasers can be up to 200 W, and the 1064-nm infrared lasers deliver up to 500 W.

Additional aspects come into play for pulsed lasers. For example, the peak power may be as important as the average output power for a Q-switched laser. Depending on the pulse repetition rate and pulse duration, the peak power may be very high even for a laser with a moderate average output power. Usually, a high average power and not only a high peak power is expected from a high-power laser.

Our high-power solid state lasers push the word “high” a bit further. High energy per pulse (1 J), high repetition rate (300 Hz), high average power (300 W) and high peak power (30 kW) together in the big brother of the family. We can manufacture our high energy solid state laser solutions with Nd:YAG or Nd:YLF as active media and use frequency conversion to deliver unprecedented laser properties in IR, green and UV while increasing the most demanding applications’ throughput.

There is no commonly accepted definition of the property “high power”; in the context of laser material processing, it usually means multiple kilowatts or at least a few hundred watts, whereas for laser displays some tens of watts may already be considered as high power. In some areas, this label is assigned simply for generating a significantly higher output power than other lasers based on the same technology; for example, some “high-powered” laser pointers emit a few hundred milliwatts, whereas ordinary laser pointers are limited to a few milliwatts.

Frankfurt Laser Company offers fiber-coupled high-power diode laser systems with up to 300 W output power. Separate diode bars are also available.
