> Injection-seeded THz-wave parametric generator (is-TPG)

Overview

Parametric generator extracts electromagnetic waves with a pair of arbitral frequency using a nonlinear optical crystal pumped by a laser.

THz wave with high spectral brightness is obtained by this is-TPG because of using single-frequency light sources both for the pump and injection seeder at the idler wavelength.

Specifications

Tuning method: Seeding source tuning
Tuning range: 0.4 - 3.0 THz
(At a pump energy 25mJ)
Head dimensions1400 x 600 x 300 mm3, 100 kg
(Including pump laser)

> THz-wave parametric oscillator (TPO)

Overview

Parametric oscillator is an efficient source of narrow linewidth light without injection seeding. "Goemon-R" TPO holds ring-type cavity with a scanning mirror on a proper pivot. This setup enables "Goemon-R" to fast frequency tuning of monochromatic THz-wave by external control.

"Goemon-R" can easily be used as a general purpose tunable source by a built-in all solid-state pump source because of the high stability and low operation cost.

> Terahertz Optics "Tsurupica"

Overview

Most of generally used optical transmission material are of no use in the specific THz-region. "Tsurupica" from PAX Inc., a well-known material for THz-region, is highly transparent not only for wide range of THz -wave but also visible light. Moreover "Tsurupica" shows almost same refractive indices in THz and visible. It realizes the precise alignment of THz light path using He-Ne laser as a guide.

Specifications

Transparent range: ~12THz (shown as right)
Refractive index: 1.53 @1~12THz, 633 nm

Refer the "Tsurupica & HR-silicon" brochure, or PAX wibsite (Japanese only) for more information.

* Tsurupica optics is product of PAX corporation.

Advantages of Tsurupica optics

A number of non-polar resins are equipped in THz region because of their small attenuation in THz. Smaller absorption of water is also important in humid environment. Some of these have good transparency both for visible and THz waves such as Tsurupica.

SO, WHY TSURUPICA?

Tsurupica only have the smallest modling shrinkage and CTE in these materials. Tsurupica also show good machinability. These characteristics guarantee high precision both for molding optics (for volume product) and machining optics (for custom product).

Comparatively high refractive index realize high NA (large diameter with small focal length) with small abberation which is often required for condenser lens in THz.

Tsurupica is the best transparent resin in THz, especially for the application which requires high precision.
