摘要： A thermo-electric laser temperature control apparatus is driven by a switching mode control circuit (317, 315). Driving current polarity (via 321 or 322) determines if the thermo-electric apparatus (305) is operating in a heat absorbent or heat generating mode. A sequencing control circuit (361-364) is used in association with the control circuit to define operative ranges of the thermo-electric temperature control apparatus consistent with maintaining proper temperature for a linear operative range for the laser. Feedback circuitry permits precision control of the converter output to limit the operative temperature range of the laser to a small precisely defined temperature window.
