Invented by H.W. Dove, Dove Prisms are also known Reversion prisms.  When the prism is rotated about its length axis, the image viewed through the prism rotates at twice the prism rotation rate.  This is an unusual and sometimes useful property for special applications. Entry and exit faces are anti-reflection coated.

Dispersion Prisms are used in applications that require separating the incident light into its component wavelengths. For example, when white light enters a Dispersion Prism, it is separated into its three components: red, green, and blue. Dispersion Prisms are ideal for spectroscopy or laser tuning.

Ytterbium-doped Potassium Gadolinium Tungstate (Yb:KGd(WO₄)₂, Yb:KGW) crystal is an excellent laser gain material, boasting numerous advantages over the widely used Nd³⁺-doped materials. Its wide spectral emission band of 1023-1060 nm enables the generation of short laser pulses (picosecond or femtosecond level). The broad absorption band at 980 nm and highly absorbent pump radiation allow it to efficiently utilize diode laser pumping. Compared with YAG doped with Yb³⁺ ions, KGW crystal has a larger absorption cross-section, which reduces the minimum pump intensity required to achieve transparency in the quasi-two-level system of Yb.

Les Lentilles Ménisques Positives sont des lentilles convexes-concaves, mais elles sont plus épaisses au centre que sur les bords. Ils sont polis au feutre et sont utilisés universellement dans l'industrie ophtalmique où la convention dicte que la puissance de la lentille soit spécifiée en dioptries. Les Lentilles Ménisques Négatives sont des lentilles convexes-concaves, mais elles sont plus fines au centre que sur les bords. Sinon, la description est similaire aux lentilles Plano Concave.

Le phosphate de titane et de potassium (KTiOPO4 ou KTP) est largement utilisé dans les lasers commerciaux et militaires, y compris les systèmes de laboratoire et médicaux, les télémètres, le lidar, la communication optique et les systèmes industriels.

Er: YAG (Erbium-doped Yttrium Aluminum Garnet) is a solid-state crystal widely used as a laser medium in various medical and dental applications. It is made by doping erbium ions into yttrium aluminum garnet (YAG) crystals and can emit laser light with a wavelength of approximately 2.94 micrometers in the infrared spectrum.

Holmium-doped Yttrium Aluminum Garnet (Ho:YAG) is an important solid-state laser crystal. Due to the excellent physicochemical properties of theYAG matrix, it can withstand high thermal loads and is an important pumpsource laser crystal for mid-wave infrared lasers. At the same time, it is alsoan ideal light source for coherent Doppler wind radar, differentialabsorption radar, and laser rangefinders.

Le LiNbO3 est largement utilisé comme modulateurs électro-optiques et commutateurs Q pour les lasers Nd:YAG, Nd:YLF et Ti:Sapphire ainsi que comme modulateurs pour fibre optique.
