Lastek: Photonics Technology Solutions

The new LDN series laser diode drivers from Lumina Power Inc are the second generation of precision CW/Pulsed diode drivers offered by Lumina Power. Building on more than a decade of experience in laser diode driver technology the new LDN family incorporates the features of the LDD and LDY models. New upgrades include increased energy storage for better pulsed performance, newly designed magnetics for cooler operation, lower inrush current at start-up and availability of an optional Performance Level “E” laser safety feature. Offered in 4 power levels from 600 to 2000 watts the LDN family of laser diode drivers offer laser designers the most advanced and proven power supply technology available.

The Lumina Power Inc LDD series is a new family of OEM laser diode drivers designed for the emerging high power laser diode industry. The LDD series is ideal for high power applications where economy is important and performance cannot be compromised. Compact size is possible due to the low-loss Zero Voltage Switching inverter and incorporation of planar magnetics. The LDD is virtually wire free.

Power factor is greater than 0.99 and conducted emissions meet stringent European regulations. No additional line filters required to meet EN 55011 emission requirements. The LDD family has been designed with the knowledge that a high power laser diode is an expensive device. Rise and fall times are strictly controlled to reduce high voltage transients which could damage the laser diode.
