Features

  • 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 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 250°C) NCPM application. The standard model accepts crystals for up to 6×6 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 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).

Applications

  • OEM Parts for pulsed laser manufacturing (communication library is provided)
  • Assuring stable-temperature controlled phase matching 
  • Protection housing for hygroscopic crystals
  • High temperature oven for NCPM
