Laser Diode Module, 658 nm, 30 mW, Analog, Circular Beam

laser diode module shown with protective cap

The LQA658-30C Laser Diode Module with Analog Modulation is a self-contained LD module with superior optical quality, a very high precision current source and a PID temperature controller, built in the module. This Fabry-Perot (FP) 658 nm typical Laser Diode Module with a 30 mW circular beam comes in a self contained module. LQA Series Laser Diode Modules can be analog modulated up to 20 MHz. To modulate the LQA Series diode laser modules from below-threshold (at 0 V) to full power (at +1 V) requires an external 1 VDC analog input. Download the user's manual for complete operating instructions. The modulation sources must be provided by the user. LQA-CAB cable is recommended for modulation interface between the modulation source and the diode laser module. This module requires a 5 VDC external power supply. A LPMS-5 Series Power Supply (not included) must be used with this LD module to meet CDRH requirements by providing an interlock input, key enable switch, delayed start-up, and laser active indicator. Warranty is not applicable when a custom power supply is used to drive the module.
