Apparatus and method for heating a small area of an object to a high temperature and for accurately maintaining this temperature |
摘要 |
A heating apparatus includes: (i) a laser providing at least one beam of light capable of heating a small area of an object; (ii) a laser driver adapted to adjust optical power of this beam of light; (iii) a photo-detector adapted to detect and measure thermal radiation from the small area; and (iv) a control loop operatively linked to the laser driver and the photo-detector, the control loop providing a signal to the laser driver to adjust optical power of the beam of light based on amount thermal radiation detected by the photo-detector. According to one embodiment of the present the laser is a CO2 laser and the small area is less than 0.25 mm in width. According to another embodiment it is a Nd: YAG laser.
