The market prospect of green laser pointer

Therefore, the semiconductor laser in the course of temperature control is essential. Set up automatic temperature control circuit (ATC) in the fiber-optic communications equipment, high power semiconductor laser includes fluid cooling or cooler, low-power semiconductor lasers can be conduction cooled or air-cooled. semiconductor laser damage to the causes and prevention measures: statistics show that the semiconductor laser sudden failure, there is great reason is due to surges and static electricity caused by a) surge: surge is a sudden moment electrical pulse, the semiconductor laser transient withstand voltage but the PN junction breakdown. The market prospect of  green laser pointer   should be analyzed.
Cleavage plane in the forward over-current transient over voltages generated by the optical power can damage even in a few nanoseconds of time exceed the maximum allowable current of the semiconductor laser, will make destruction and damage. Produce surge causes and preventive measures: a laser diode driver no slow start, on and off circuit, finishing Optoelectronic Equipment Co., Ltd. to collect data from Shaanxi in the circuit the formation of a transitional process, ie turned on, the drive power to the magnitude of the overshoot, stabilized subsequently over-process. current overshoot of this drive easy to make the PN junction was electrical breakdown, damage or destruction of the cleavage plane was light even if the surge intensity or duration will not the first time you open the power to make lasers produce complete failure. It is enhancing the process of green laser pointer  .
But also in the number of surges under the impact of accelerated semiconductor laser performance degradation and final failure. Therefore, the semiconductor laser drive power should adopt measures to slow start. Semiconductor laser tube socket by welding, but directly into the socket in order to facilitate the replacement of the tube sockets and socket of poor contact will cause the pass off arising from contact with the process of voltage surge. To do this, make sure that the semiconductor laser tube have a good and reliable electrical contact. the slow start circuit of the semiconductor laser and semiconductor laser capacitor capacitance excessive or capacitance charging voltage is too high, then turn off the power when the capacitor discharges can cause semiconductor laser over-current, so that the PN junction breakdown occurred cleavage plane is damaged. The sales situation of  green laser pointer   should be recorded.
The string into the drive circuit and the external circuit of the semiconductor laser drive circuit associated surge, resulting in laser breakdown should not be a laser diode driver circuit associated with the start frequently contain large capacitive or inductive load line between in order to pro forma surge noise filter to isolate some users required use of semiconductor laser frequency and or need to use the potentiometer to adjust the laser drive current and output power, if the potentiometer sliding contact in the sliding process, mechanical or dust caused by poor contact will lead to surge, laser hazards, so you want to check and selection of good potentiometer in order to prevent inadvertently missed in the adjustment process. It is the data and documents of  green laser pointer  .
The drive current to exceed the allowable rated current and damage the laser, suitable with the potentiometer in series a current limiting resistor, adjust the potentiometer overshoot to a minimum resistance at the fixed resistor to limit current still allows the value of this information by the Shaanxi Optoelectronic Equipment Co., Ltd. has collected 3 range. need electric iron pin semiconductor laser drive circuit welding, such as electric iron leakage, the surge to make the laser damage. To do this, you should use the shell (which also include reliable protective earthing measures electric iron tip), best to use the tip electric leak not occurred induction potential and grounded soldering irons can also use the Battery iron as a precautionary measure, but also to be iron to normal temperature after power failure immediately welding. The data and document of  green laser pointer is the basic information.
