Nonlinear Crystal Oven
Description
Nonlinear crystal (NLC) materials which are used in higher laser frequency generation requires phase matching to be kept in stable temperature conditions, therefore crystal holder plays key part in this role. To avoid temperature drift, issues with water absorption for hygroscopic crystals, temperature of NLC needs to be controlled by a stable crystal oven.
Most of the NLC materials uses angle tuned phase matching, therefore crystal holders, depending on interaction type (Type I or Type II) shall have XY angle tuning. Some of NLC can be also oriented for Non Critical Phase Matching (NCPM). The NCPM requires high temperature ovens, which phase matching is tuned by means of precise temperature.

Features
The Digital Thermo Control (DTC) nonlinear crystal oven models DTC-A, DTC-B, DTC-C and DTC-HT have excellent temperature control stability of +/- 0.1°C in the range of 30–220°C, at the same time assuring precise and stable mechanical angle-tuning construction.
The DTC–A model ovens are designed and recommended for crystals with apertures 2×2, 3×3, 4×4, 5x5mm and length up to 30mm.
The DTC-B is specified for crystals with apertures 6×6, 8×8, 10×10, 12×12 and 15x15mm, length up to 30mm.
Larger aperture size and length exceeding 30 mm of 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 bigger. 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 via Geola Thermo-Tool software provided along with any of DTC oven model.
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).
