Second-harmonic generation may be utilized to achieve frequency of double or higher.

They are up to 20 times more efficient at second-harmonic generation than crystals of the same material without periodic structure.

Upconversion should be distinguished from two-photon absorption and second-harmonic generation.

One of the most commonly used frequency-mixing processes is frequency doubling or second-harmonic generation.

Among these techniques, second-harmonic generation and sum frequency generation spectroscopy are best known and also widely used by scientists from various fields now.

Used in optical modulators and for non-linear optics such as SHG (second-harmonic generation).

In the following examples, the autocorrelation signal is generated by the nonlinear process of second-harmonic generation (SHG).

A crystalline solid displaying second-harmonic generation was generated by including a nonlinear optical chromophore in a chiral metallacrown compartment.

A specific nonlinear optical technique called second-harmonic generation (SHG) has been recently applied to the study of conformational change in proteins.

Optimized Second-Harmonic Generation in Quantum Cascade Lasers.

These crystals have been custom fabricated (in collaboration with staff of EEEL) to obtain efficient second-harmonic generation and sum/ difference frequency generation.

Optical poling of silica fibers allows for second-harmonic generation through the creation of a self-organized periodic distribution of charges at the core-cladding interface.

However, it is prone to photochromic damage (called grey tracking) during high-power 1064 nm second-harmonic generation which tends to limit its use to low- and mid-power systems.

Second-harmonic imaging microscopy (SHIM) is based on a nonlinear optical effect known as second-harmonic generation (SHG).

This is because in second-harmonic generation, only one input light beam is required, but if ω ω, 2 simultaneous beams are required, which can be more difficult to arrange.
