All PSoC Application Notes

AN2062: Laser Diode Controller

1.Build a laser diode controller module using PSoC. a. A stability of +/- 0.05 dB @ 0dBm (1 mW) optical power output b. Provide a facility to modulate the laser Advantages in using the PsoC 1.A higher level of integration,contains all the building blocks needed. Consequently you fiddle with only a few components. Also results in smaller PCB real estate requirement. 2.Knocks off about 20 - 30 dollars from a typical handheld laser source, eliminating things like digital potentiometers, which in turn need a microcontroller to use, temperature controller, some analog devices and a few TTL IC's. 3.A complete laser controller can be built using just the analog functions of a PsoC controller. The additional functions for a handheld laser source like ,modulation etc may be done in software. 4.Additional options like over current protection and thermal protection may be added using the comparator and FlashTemp user modules respectively. Thermal shutdown may be added if the unit need operation in conditions other than normal operating temperatures.
