Description
The Digital Thermo Control (DTC) nonlinear crystal oven models DTC-A, DTC-B, DTC-C and DTC-HT have excellent heating stability of +/- 0.1ºC in temperature range 30–71ºC.
The DTC–A model ovens has mechanical structure designed for crystals with apertures 2×2, 3×3, 4×4, 5x5mm.
The DTC-B specified for crystals with apertures 6×6, 8×8, 10×10, 12×12 and 15x15mm.
Larger aperture size nonlinear crystals are supported by DTC-C oven.
The new DTC-HT model designed for high temperature (up to 220°C) NCPM application. The standard model accepts crystals for up to 6×6 mm apertures and up to 50 mm in length.
On request we can manufacture ovens for crystals with aperture up to 60×60 mm or even larger. Each oven model is optimized for best performance at up to specified crystal aperture sizes.
Example of DTC-HT application:
LBO Type I NCPM SHG @ 1064 nm (θ=90°, φ=0°), T = 149 °C
Temperature settings are stored in internal memory of thermo controller and can be easily changed via USB cable inside Geola ThermoTool software provided together with DTC oven. After temperature is set and DC 24V power supply is applied, oven works in completely autonomous regime, DTC doesn’t require any cable connection with PC.
