Description
The Digital Thermo Control (DTC) nonlinear crystal oven models DTC-A, DTC-B, DTC-C have excellent temperature control stability of less than +/- 0.1°C in the range of 25–71°C, at the same time assuring precise and stable mechanical angle-tuning construction. The new DTC-HT model stability is +/- 0.005°C in the range of 25–250°C.
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 250°C) NCPM application. The standard model accepts crystals for up to 22×22 mm apertures and up to 50 mm in length.
The new DTC-GIANT model designed to secure and stabilize large size nonlinear crystals, for example KDP/DKDP crystals. The DTC-GIANT model is fully customizable and accepts crystals with apertures from 50x50mm to 200×200 mm or more and up to >50 mm in length.
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.
