KGW Crystal - An Overview

]. Mainly because of the quick storage time, Ti:sapphire is often pumped by frequency-doubled Nd:YAG or Nd:glass strong-point out lasers, which results in a bulky and complex program with high Price. In comparison with typical CPA laser methods, the OPCPA process can obtain a shorter pulse period and a higher peak ability.

The thermal conductivity of frequent double tungstates is with the buy to three–4 W/(K m) �?which is not lousy when compared with other laser crystals (Whilst quite a few instances a lot less than for YAG), and rather massive when compared While using the thermal conductivity of normal Eyeglasses.

For some apps, tungstates provide a combination of various beneficial properties. Particularly for passive manner locking, ytterbium-doped double tungstates are often excellent to other media when it comes to The mixture of large acquire bandwidth, big cross-sections, and relatively good thermal Attributes �?Regardless that in Every individual self-discipline far better products may very well be found.

In its elemental sort, potassium includes a silvery gray metallic overall look, but its compounds (like potassium hydroxide) tend to be more often used in industrial and chemical programs.

-switched method. The bandwidth while in the orthogonal orientation was Evidently much broader. The click here calculated Fourier renovate minimal pulse length was as quick as sub-one hundred sixty fs. Beneath the configuration where by The 2 crystals were being placed in a similar orientation, Together with the seed enter, the amplified pulse bandwidth was only three nm with 180 μJ Vitality when it broke the dichroic mirrors.

Ahead of the development of Nd:YAG, Nd3+:CaWO4 was an important unusual-earth-doped laser gain medium. It was in reality used in the first consistently running crystal laser.

Sooner or later, We are going to adopt a laser seed using a broader spectral bandwidth and use an acousto-optical programmable dispersive filter to modulate the seed’s spectrum to create total use with the gain bandwidth of our regenerative amplifier.

Thermal consequences are substantially scaled-down in KGW. This combined with the substantial hurt threshold make the crystal a superb prospect for ability scaling. Comparing Ba(NO3)two and KGW for Raman software Ba(NO3)2 are more effective in the event of ns pulses and KGW �?in the event of ps pulses.
