Our laser drivers are used to driver diode laser. There are kinds of laser drivers, such as low noise low current, high efficiency medium current, AC input high current high efficiency, high current short pulsed, etc. Take ATLS1A103 as an example. This diver is an ultra-low noise laser driver.

The physical photo of laser driver
Since the maximum power consumption of this laser driver is less than 1W, no heat sink is required by this laser driver. This laser driver comes with a temperature compensation network, so the output current keeps the same as the temperature rises of the controller. There is also a protection circuit inside the laser driver, so it will shut down itself when the laser driver temperature is higher than a limit, 120°C. This will prevent the laser driver from being overheated and damaged.

How to improve the processing performance of thermoelectric cooler（Ⅱ）

3. Guarantee fixture clamping force, flatness and parallelism
From the reason for generating weld resistance, in order to reduce weld resistance, the size deviation of TEC element should be as small as possible. At the same time, the fixture clamping force should be moderate, the flatness should be less than 0.03mm, and the parallelism should be less than 0.05mm. When soldering, spring pressure should be changed into reed pressure in order to ensure that pressures of two ends are same.

4. Optimizing weld process
During welding, it needs to ensure that temperature field is uniform. After meeting the welding requirements, solder melting time should be reduced as far as possible to decrease thermal shock. In order to reduce the temperature stress caused by shrinkage, cooling curve should be properly optimized.

5. Reducing the amount of solder
Based on meeting the requirements of weld strength and weld resistance, the amount of solder should be reduced as far as possible.

Our company specializes in design and produce TECs, TEC controllers and some other productsrelated TECs. Before our products go into market, they will go through strict design, testing and verification, so you can completely trust us. What’more,we can also customize your TECs based on thermal system.
