Features

Analog Modulation Versions

The LQA Series can perform analog modulation of 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.

Digital Modulation Versions

The LQD Series can perform digital modulation (via TTL) of up to 100 MHz. To modulate the LQD Series from below-threshold to full power requires a user-supplied external 0-5 V TTL modulation signal (0 V yields full power).

Wide Variety of Laser Modules

The laser diodes are available at various wavelengths and output power levels. Newport strives to offer high performance laser diodes with a variety of different output wavelengths and a high output power and beam quality to provide the maximum flexibility in your research.

Current Source and Temperature Control Built-in for Excellent Performance

The LQA and LQD Series includes self-contained laser diode with superior optical quality, a very high precision current source and a PID temperature controller, built in the module. These laser modules are ideal for demanding experimental setups where the temperature and the current control are important.

Elliptical or Circular Beam Output

All the diode lasers are available either in elliptical (the E versions) or circular beam output (the C version). The wavelengths indicated are typical values only, due to the nature of FP lasers. Circular beams are generated using a micro lens built in the diode laser and exhibit better quality than elliptical versions.

Applications

  • Spectroscopy
  • Interferometry
  • Machine vision
  • Marking, Flow cytometry
  • Tissue fluorescence.

LPMS Power Supplies Recommended for Use with Laser Diode Modules

Newport's LPMS Series Power Supplies are not just power supplies. This is a key instrument that will make the LQA and LQD laser diode modules CDRH compliant. It provides an interlock input, key enable switch, delayed start-up, and laser active indicator. The laser modules in the wavelength range of 375-473 nm require an 8/12 VDC power source. Those in the range of 635-2330 nm require a 5 VDC power source. Warranty is not applicable when a custom power supply is used to drive the module.
