Fulfilling the requirements of iec60601 for electrical safety the laser diode drivers can even be fitted in medical systems.

The lddhc series high power laser diode driver is a new family of oem laser diode drivers designed for the emerging high power laser diode industry. The alphalas picopower ld series of picosecond pulse diode lasers with driver are generating short laser pulses with wavelengths ranging from 375 nm to 1550 nm as well as custom specific wavelengths. Outputs can be ganged together to achieve peak total current greater than 36a.

China high frequency diode laser of with ce. High current laser diode driver dedicated for 20 w 40 w 60 w and other similar power laser diodes. It is the most compact device with such performances and this makes it an ideal tool for rd labs or oem integration into your product.

The isl58303 is a high speed triple output laser diode driver designed to support color field sequential laser light source pico projection modules. Our picosecond pulse diode lasers deliver pulse durations below 40 ps and peak powers can exceed 3 w. The possibilities for driving high power laser diode bars and stacks at high frequencies has been shown.

It is important to maintain a constant impedance at the cathode of the laser diode such that the load on the high speed output circuit versus frequency will remain stable. Diode drivers employing intelligent high frequency switching circuitry to produce the output current pulse are much more tolerant of changing operational conditions and also are inherently more efficient than linear diode drivers. Standard units can provide from a few watts up to 400w at a maximum of 100a while high power units supply a stable and highly accurate 600 1000 or even 1500w.

With output currents to 200amps the lddhc series high power laser diode driver is available in 3 power levels and a wide range of compliance voltages. This high power laser diode driver delivers precision cw or pulses which are generated internally by an on board pulse generator or on demand from an external analog modulation signal.
