The over heat might make laser pointer get aging too fast

The over heat might make laser pointer  get aging too fast.
The discharge voltage is too high, bring difficulties to the higher frequency of high-voltage power supply developed. In order to improve the performance of the CO2 laser, to overcome the shortcomings of DC excitation, and the exchange of high-frequency discharge CO2 laser technology. Frequency discharge frequency usually in the dozens - hundreds of kHz circuit can be used transistors and high-frequency transformer of the inverter switching power supply. The high-frequency-excited CO2 laser power was originally started from a lower frequency. 10kHz AC power in 1977, the former Soviet Union as an incentive power of the laser output. In 1988, the Japanese developed a square tubular electrode structure of the 2.5 kW fundamental mode CO2 laser power supply frequency of 100kHz. And at the same time,  laser pointer  can be use in some other special locations and applications.
The experiments show that high-frequency discharge excitation to improve the stability of the discharge, no matching measures, did not add any ballast resistors to obtain a large area uniform glow discharge. All-transistor power reduces the volume of discharge excitation means that the technology has the potential to increase the output power, provides a new way for the miniaturization of the CO2 laser. RF-excited CO2 gas laser technology, a new direction, has a completely unique advantage has been a rapid development in the past 20 years. The outstanding advantage of the RF excitation technique: RF gas discharge has a positive volt-ampere characteristic, can achieve sustained discharge. The client uses  laser pointer for the practical or entertainmental purposes.Performance of the green  laser pointer was not that stable
High utilization of electrical energy; stable discharge can be a large area of uniform discharge; high injection power density, the volume of the device greatly reduced; low working voltage help to improve the device lifetime, and the use of safety; radio waves to high-frequency amplitude modulation. The high degree of control of the output optical power; the flexibility to achieve the conversion from continuous to pulse and the pulse width and pulse frequency regulation. RF excitation frequency range of 1MHz to hundreds of MHz of the first RF power to coil around the waveguide, although the laser output can be uneven, but the discharge, poor coupling efficiency, the coil inductance. With the development of high-frequency electronic technology, the RF excitation power technology progress. The end button of laser pointer is the constant on switch.
