By Gang Liu, Nan Shi, and Hongtao Zhou, Analog Technologies, Inc. Chopping a laser beam is often a necessary practice. For a diode laser, it is much simpler and less costly to chop the beam electrically, rather than mechanically. The output laser beam power, PO, versus the laser diode input current, ILD, characteristics are shown in Fig. 1. Fig. 1 Output Laser Beam Power vs. Laser Input Current In this figure, PO is the optical output power of the laser diode; ILD is the laser diode input curren...(more)
TEC modules have two types, one is standard TEC module, and the other is long life TEC module. The former is used for normal applications of heating and cooling objects, and the latter can be used in thermal cycling applications. Thermal cycling applications refer to those with frequent changes between heating and cooling. In these applications, TEC modules are exposed to demanding physical stresses when they shift from heating to cooling. This will significantly reduce the operational life of a...(more)
Thermal cycling TECs refer to those TEC modules that can be used in thermal cycling applications. Usually TEC modules are used for cooling down or heating up objects, and the life time of TEC modules will be largely reduced when they suffer frequent shifts between heating up and cooling down. Therefore, for thermal cycling applications , including PCR devices, thermal cyclers, chillers and analyzers, etc, TEC modules like ATE1-TC-31-3AS are the best choice. This TEC module ATE1-TC-31-3AS comes w...(more)
ATLS1A104 is a low noise laser diode driver that is designed for driving laser diodes. This laser driver has the largest current among 104 series laser drivers, and the current value is 1A. It has a low noise, 0.6mARMS@ 0.1Hz ~ 10Hz, and doesnt require heat sinks to dissipate heat. This laser diode driver has independently programmable IOUT and IOUT limits and loop good indication function. It is integrated with a controller internal temperature monitoring function, which will shut down the cont...(more)
ATLS250MA104 laser diode driver is one of 104 series laser drivers that are developed by ATI. This laser diode driver comes with a maximum output current of 250mA and a low current noise, 0.6ARMS@ 0.1Hz ~ 10Hz. When powered by a power supply of 5V, the output voltage is from 0.5V to 3.6V. This laser diode driver has a temperature compensation network, which can keep the output current to be the same even when the laser diode driver temperature increases. Moreover, this laser driver comes with a...(more)
Laser diode driver are designed for driving various types of laser diodes. For years, ATI has been dedicated to developing and manufacturing multiple types of laser diode drivers. ATLS100MA104 laser diode driver is a newly developed laser driver. This laser diode driver comes with more features when compared with our current low noise laser drivers. It comes with independently programmable output current and output current limit, loop good indication, controller internal temperature monitoring,...(more)
ATI develops and manufactures various types of Peltier controllers, or so-called TEC controllers, which are designed and used for driving thermoelectric coolers, or TECs. This TEC controller comes with high stability, high energy efficiency, zero EMIs and compact size. This controller is packaged in a 6-side metal enclosure which blocks EMIs from outside. This TEC controller can output up to 4A current and the maximum output voltage is the power supply voltage minus 0.2V. The TEC controller prov...(more)
There are various types of laser diode drivers in the market, and most of them have a large size. There is an urgent demand for small size laser diode drivers, thus ATI develops some new laser diode drivers including DC input and AC input ones, both of which have a small size, and the former is smaller than the latter. AAS40A4V2 is one of AC input laser diode drivers. As the part number AAS40A4V2 indicates, the maximum output current is 40A, and the output voltage is 0V ~ 4V. This laser driver c...(more)
