TK1 and KK1 is high temperature set (up to 200 °C) consisting of thermocontroller TK1 and crystal oven KK1. TK1 has two independent outputs and can control two KK1 ovens simultaneously.
Trough RS232 computer interface it can be controlled from PC. Current temperature is shown on LED display.
The nonlinear crystal is mounted into adapter before insertion into oven KK1. Such design facilitates handling and replacement of the crystal.
The non-linear crystal can be sealed with fused silica windows in order to provide extra protection.
The standard adapters are 15, 30 and 50 mm. long with apertures of 3x3, 4x4, 5x5, 6x6 mm. size.
By custom order adapters for crystals up to 12x12 mm size are available. In addition, adapters for Brewster-cut and PPLN crystals are available too.

TK3 is 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. TK3L model can fit crystals with up to 30 mm long.

Each oven is made exactly for specified crystal, so it cannot be used for different size crystals.

TK4 oven has identical mechanical design as TK3.
The pre-set temperature can be adjusted in ±5°C range by the help of potentiometer.
The current temperature is not indicated.
In addition, TK4 has “temperature ready” output signal, changing state when pre-set temperature is reached.
TK4XL model can fit crystals with up to 50 mm long.

TK7 is compact oven with build-in thermocontroller for temperature up to 60 °C.
TK7 oven provides more crystal mounting options in comparison to TK3 or TK4. Like in KK1, each crystal is mounted into adapter before insertion in oven.
TK7 and KK1 crystal adapters are compatible.
Maximum crystal size for this model is 12x12 mm. and the length of the crystal - 30 mm. The pre-set temperature can be adjusted in ±5°C range by the help of potentiometer.
The current temperature is not indicated.
TK7 has “temperature ready” signal, changing state when pre-set temperature is reached.
For additional protection of crystal surfaces from the dust or other contamination, we offer TK7 model – windowed version of TK4 oven.

With combination of temperature controller, TK10 series ovens are designed specifically for tuning and conditioning the periodically poled bulk devices (PPSLT, PPLN & PP-MgO:LN) and other nonlinear crystals.
The oven is designed to hold the crystal with dimensions of 30×16×1 mm. Custom made oven is also available. The crystal heater provides temperature stabilization for crystals with an accuracy of 0.1°C.
The crystal temperature can be change from 50°C to 200 °C.

• Crystal’s temperature stabilization
• Fast temperature control using active cooling
• External temperature kept low by insulation – no need for gloves
• No alignment is required when crystal is removed and replaced
• 4 screws to remove to exchange crystals
• Crystals can be removed without removing the oven from the experiment
• LabVIEW based software included

Applications

• Fast temperature tuning of generated wavelengths in periodically oriented and noncritical phase-matching nonlinear crystals
• Temperature tuning of Bragg grating wavelengths
• Thermostat of tuning temperature
