Gray Track Resistant (GTR) KTP crystals developed by hydrothermal method overcomes the common phenomenon of electrochromism of the flux-grown KTP, thus has many advantages such as high electrical resistivity, low insertion loss, low half-wave voltage, high laser damage threshold, and wide transmission band. So it's very suitable for high power density applications, where regular flux-grown KTP crystals will suffer from gray track damage.GTR-KTP crystal has gray track resistance sufficiently greater than typical flux-grown KTP.

Polarizing Beamsplitters (PBS) splits incident unpolarized light into two perpendicular linearly polarized light. Among them, p-polarized light passes through completely, while s-polarized light is reflected at 45 deg which makes the emitting direction of s-light vertical to p-light. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction:cube or plate.Cube PBS are fabricated using two typically right angle prisms.

The periodic polarized KTP (PPKTP) is a novel nonlinear optical material that can be customized to achieve all of the nonlinear applications required in the entire KTP crystal transmission band, without the phase matching limitations of conventional KTP. Moreover, the effective nonlinear coefficient of PPKTP is about 3 times higher than that of conventional KTP. In the nonlinear application of conventional KTP, the crystal must have a single domain structure, but PPKTP crystal has an artificially induced periodic domain structure.

An aspherical lens features a non-spherical but rotationally symmetric shape with a curvature radius that changes at various points between the center and the edge. Although producing this type of lens is difficult, when manufactured properly, it offers greater functionality than a comparable spherical lens.Spherical Lenses vs. Aspherical LensesSpherical lenses have a spherical surface and the same radius of curvature across the entire lens. In contrast, aspherical lenses have a more complicated surface with a gradually changing curvature from center to edge.
