Zoom Laser Beam Expander
EKSMA OPTICS offers compact Galilean type zoom beam expanders for Nd:YAG lasers fundamental and its harmonics wavelength: 1064 nm, 532 nm and 355 nm. Zoom beam expander provides variable expansion ratio of 2x-8x or 1x-8x with adjustable focus to correct for laser beam divergence.
Compact Laser Beam Expanders
The Compact Beam Expander is designed to increase the diameter of a collimated input beam to a larger collimated output beam. EKSMA OPTICS offers compact Galilean type beam expanders for 1064 nm, 532 nm and 355 nm wavelengths. The Compact Beam Expander has a possibility to be adjusted for the input beam divergence angle to obtain collimated, divergent or focused beam at the output.

Nonlinear and Laser Crystals- Crystals for Stimulated Raman Scattering
Model KGW - Raman Scattering Crystals for Laser Frequency Conversion
EKSMA OPTICS offers crystalline materials - Barium Nitrate - Ba(NO3)2 and undoped potassium gadolinium tungstate KGd(WO4)2 or KGW which have attracted much interest as most suitable crystals for stimulated Raman scattering (SRS). These materials can be used for frequency conversion in lasers for extending of tuning range. SRS in crystals is compatible with current all-solid-state technology and provides a very simple, compact means of frequency conversion.
Nonlinear and Laser Crystals- Ovens & Holders
Model TC1 - CO1 - Temperature Controller with Oven
TC1 together with CO1 is a high temperature set (up to 200 °C) consisting of thermocontroller TC1 and crystal oven CO1. TC1 has two independent outputs and can control two CO1-30 ovens simultaneously or one CO2-50 oven. Trough RS232 computer interface it can be controlled from personal computer. Actual crystal temperature is shown on LED display. The nonlinear crystal is mounted into adapter before insertion into oven CO1. Such design facilitates handling and replacement of the crystal. The nonlinear crystal can be sealed with fused silica windows in order to provide extra protection. The standard adapters are 15, 30 and 50 mm. length with apertures of 3x3, 4x4, 5x5, 6x6 mm size. Customized adapters for crystals up to 12x12 mm size are available. In addition, adapters for Brewster-cut and PPLN crystals are available too.
Heatpoint Oven for Nonlinear Crystals
Heatpoint is a compact round oven designed for heating of nonlinear crystals and keeping them at their optimal operation temperature. It is also suitable for thermo-stabilization of crystals with low thermal acceptance. The oven could be used for heating of LBO, KTP, DKDP or other crystals. Oven`s temperature is preset and can be chosen up to 80 °C.
Model CH3 - Oven for Nonlinear Crystals
CH3 is a compact oven with build-in thermocontroller for temperature up to 60 °C. It is ideal for larger aperture crystals like KD*P. The crystals with up to 15 x 15 mm dimensions can be mounted. CH3-30 model can fit crystals with up to 30 mm length. Each oven is made exactly for specified crystal, so it cannot be used for different size crystals.
Open Ring Holders
Ring mounts made of black anodized aluminum are available for safe and convenient handling of nonlinear crystals. Holder 830-0001-06 comes with white anodized aluminium adapter, crystals have to be glued into it. No glue is used for fixation of the crystal into other open ring holders, which are provided with teflon adapters. The standard sizes of ring holders are Ø25.4 mm or Ø30 mm with thickness range from 6 mm to 17.5 mm depending on crystal size.
