AVX-S3B Laser Diode Bias Insertion Unit with Socket

AVX-S bias insertion units (or "output modules") provide a simple but effective way of connecting a laser diode to a pulse generator and a DC bias. The user-supplied laser diode is inserted into a specially-designed high-speed socket included on one side of the AVX-S unit. The socket is optimized to provide minimal rise time degradation. The AVX-S bias insertion unit includes the necessary networks to match the laser diode to the pulse source (typically an ultra-fast Avtech pulse generator). Contact Avtech for recommended pulse generator / output module combinations. See also the Avtech AVO-9 series of laser diode drivers - each AVO-9 laser diode driver includes a matched AVX-S output module. Avtech can accommodate common laser diode packages from Lumics, Qphotonics, Fitel, Fujitsu, Mitsubishi, Bookham, Ulm Photonics, Nichia, and others.

To form a valid model number:

AVX-S3B
+ (select one: -P0, -P0C, -P0D, -P1, -P1B, -P2, -P2C, -P2D, -P3, -P4, -P4B, -P5, -P7, -P8A, -TO3)
+ (recommended optional accessory kits: -AK1, -AK8)
+ (select one, or none, from: -T1B, -T4B)
+ (other possible options: -MD)

Each model is customized for a specific diode's pinout and I-V characteristics. If a generic pinout option (e.g., -P0, -P1, -P2, -P3, -TO3) is selected, then a drawing showing the diode package size and electrical pinout must be provided by the end-user, and the model number and price may change. If a specific pinout option has been selected (-P1B or -P1C, for instance), no additional information is required.

Some options may not be available with all formats (see the table above), and some combinations of options may not be available together. See the data sheet for details.

Our online Model Number Checker tool can be used to validate model numbers.
