Laser diodes for material processing & laser cutting applications
The low noise LD15CHA, the newest addition to the Wavelength laser diode driver line, offers modulation bandwidth, and power for materials processing, industrial laser cutting, and laser diode bars / stacks. The small laser diode driver delivers 15A output current up to 28V. It meets laser compliance requirements from 3V with a single 5V supply, and up to 28V with an additional 30V power supply.
Additional models are available with 2.5A, 5A, and 10A output. This product family supports A & B type laser diodes. Three photodiode current ranges are available.
FEATURES AND BENEFITS
➢ Up to 15A output current
➢ Dual supply operation up to +30VDC (28V maximum to laser)
➢ Constant Current or Constant Power Mode
➢ Bandwidth 600kHz (3dB at Full Current, Constant Current Mode, Sinewave)
➢ Stability: <200ppm (CC) and 0.03% (CP).
➢ RMS Noise Current as low as 35μA at 100kHz
➢ Noise current density: 100nA/√Hz.
➢ Safety:
initial configurations can be made prior to enabling current to the laser
adjustable clipping current limit ensures that output current will never exceed the user-set limit
slow-start and delay circuitry
brownout protection
over-/under-voltage protection
➢ Simple wiring using spring-loaded terminal strips
➢ Easily mounted to an optics table or Wavelength heat sink
