AixiZ is a licensed laser manufacturing and service company, Texas license # Z02107. Federal supplier cage code 4MF77. You are purchasing one LASORB EDS protection system for laser diodes for blue (405/445/455) frequencies. AixiZ is an authorized distributor of Pangolin products. GENERAL APPLICATION INFORMATION LASORB is a device that is specifically designed and tested to protect laser diodes from ESD and power surges. LASORB overcomes the problems of previously-known ESD protection schemes by preventing reverse-bias of the laser diode under all conditions, and also by preventing ESD or other power-related faults from exceeding the maximum forward-bias voltage of the laser diode. LASORB is able to do this while not adding significant resistance or capacitance to the laser system. CONNECTING LASORB TO THE LASER DIODE LASORB is connected directly to the terminals of a laser diode. The LDA terminal is connected to the Laser Diode Anode, and the LDK terminal is connected directly to the Laser Diode Cathode. LASORB should be connected as closely as possible to the laser diode – certainly no greater than one centimeter away, thus preventing stray inductance in between the laser diode and the ESD protection means. NEGATIVE-ESD AND REVERSE-BIAS PROTECTION LASORB includes a fast-acting diode – the cathode of which is connected to the LDA terminal. The fastacting diode within LASORB has been proven to be generally more robust than a Schottky diode, which is typically used in an attempt to protect a laser diode. The fast-acting diode within LASORB is able to protect a laser diode against ESD whose polarity would tend to reverse bias the laser diode, and also protect the laser diode against pulsed or continuous reverse bias (also known as reverse polarity) conditions. Normally reverse bias only occurs during an ESD event, or when the power supply is turned off. As long as the reverse bias condition does not exceed 2.9 amps RMS or 50 amps peak, no additional reverse bias protection will be needed. POSITIVE-ESD AND POWER SURGE PROTECTION LASORB also includes a slew-rate detector, which monitors the voltage between the LDA and LDK terminals. If the slew-rate is faster than a limit that is predetermined for each specific LASORB part number, LASORB will conduct current between the LDA and LDK terminals, thus conducting current away from the laser diode. Using the slew-rate detector, LASORB is able to discern between normal laser diode operation, and a power surge or ESD event. LASORB also includes other circuitry to enhance its ability to discern between normal drive conditions and ESD and, because of this additional circuitry, LASORB is able to protect the laser diode whether power is applied or not. LEAKAGE CURRENT WHILE INACTIVE The LASORB device has several degrees of freedom that Pangolin can optimize for a particular type of laser diode and application. One of the degrees of freedom is the leakage current apparent when LASORB is inactive (not responding to an ESD event). Generally speaking, higher levels of leakage current will allow LASORB to better-protect the laser diode while it is lasing. The leakage current is not temperature dependent and it appears almost purely resistive. If desired, Pangolin can minimize this leakage current to levels so low, that it appears like a 5 Gig-ohm resistor (1 nA leakage at 5 volts). In such cases, the ESD protection offered by LASORB is reduced while the laser is lasing. Nevertheless, ESD protection is still present and very impressive, even though it is reduced when compared to LASORB models with higher levels of leakage current. MODULATION CONDITIONS AND PART NUMBER RECOMMENDATIONS Within this datasheet, we use to the term “current-modulation” to indicate those drivers that maintain a continuous voltage bias across the laser diode, and only change this voltage slightly during modulation. We use the term “voltage-modulation” to indicate those drivers that completely remove and re-apply the nominal terminal voltage across the laser diode during modulation. In typical laser diode drivers (ones which use current-modulation), the voltage across the laser diode terminals typically changes very little even during modulation. However, some laser diode drivers (ones which use voltage-modulation) effectively remove, and then re-apply the nominal terminal voltage (typically 2.2 to 5.0 V) across the laser diode over and over again. This 100% voltage-modulation may fool LASORB into believing that there is a power surge condition, and when this happens, LASORB will conduct current for a brief time, potentially interfering with modulation. To avoid this, you should choose a specific LASORB part number that corresponds with the maximum expected voltage-modulation rate. However, if the laser diode driver does not perform 100% voltage-modulation, then practically any LASORB part will work, and the modulation rate will be primarily dictated by LASORB device capacitance. Since the dynamic impedance of a typical low power red laser diode is well under 5 ohms, the maximum modulation rate is greater than 25 MHz when using current-modulation techniques. For higher power red laser diodes whose dynamic impedance is less than 1 ohm, modulation rates well beyond 100 MHz are possible. For best results and part number recommendations, it is recommended that OEMs contact Pangolin for applications advice and laser diode driver review.
