TERMIONA has developed unique system intended for direct forced cooling of TO-3 laser bodies based on CERATOM® technology. The system in question is manufactured in kind of double-stage module with liquid cooling system to provide heat outlet for the maximum efficient cooling thereof. TERMIONA thermoelectric system is in a position to adjust laser temperature in a rather wide range whereas vacuumizing its internal volume excludes the opportunity of occurrence condensate and accumulated frost. Difference in temperatures between cold plate of first module and hot plate of second module may reach 60º С.
To exclude the opportunity of condensate occurrence in TO3 laser body cooling system the entire subject system is enclosed in the properly sealed body and connected to vacuum pump. To facilitate more efficient system operation and increase its maximum admissible production capacity in a quality of finishing circuit any liquid cooler with suitable cooling parameters is used.
Technical specification:
| Parameter name | Value |
| Working crystal temperature | -25º С to +35º С (accurate within 2º С) under the ambient temperature -50º С to +50º С |
| Efficient cooling capacity | up to 100 W |
| Overall dimensions | 150х150х200 mm |
| Weight | 5 kgs |
The evident advantages of our unique forced cooling system for body of TO3 laser based on CERATOM® technology developed by TERMIONA may be generally outlined as follows:
- lower device weight in comparison with immediate analogs thereof (by 15 to 30 percent);
- reduction of thermal overheat of active thermoelectric components;
- improved cooling reliability;
- opportunity of the additional increasing capacity of solid-state semiconductor instruments by 50 percent in comparison with cooling systems based on ceramic modules;
- opportunity to provide cooling of instrument body without any intermediary heat conductors.
