1500W high power laser diode driver LDD-1500 is a series of drivers. It was designed to provide current by pulses or in continuous form to laser diodes, laser diode bars and stacks.
Several variants of LDD-1500 are offered with different maximum output power (Pmax could be 600, 1000 or 1500 W), maximum output current (Imax range is 10 … 100 A), maximum output voltage (Vmax ≤ Pmax/ Imax), selected at the moment of order. For more detailed information see user manual.
Devices are encased and easy for the user to mount, they run on common 100‑240 V AC or 200‑240 V AC 50/60 Hz. So you don’t need any extra power supply for the driver.
An output current level can be programmed in working range by user applying a DC voltage to the respective pin. Base interface to control LDD is analogue (15 Pin “D”-Sub Female). An external low voltage TTL signal from pulse generator gives precise control over pulse width, repetition rate, and duty cycle, allowing for customization to meet specific application requirements.
It is also possible to control the module through an additional external remote control assembly LDD-RC (sold separately), or through an additional external PCBs (should be purchased separately), either stand-alone (ordering code – STA) with jumpers and trimpot or driven by a computer through RS‑232 interface (ordering code – RS232).
1500W laser diode driver can be used for industrial, laboratory, and, in some cases, for medical applications. For the proven compliance to standards for a certain modification the certification procedure is need to be passed, which is available on demand.
The high power laser diode driver LDD-1500 is interesting for industrial laser systems and scientific research, where high-power pulses are essential for tasks such as material processing.
The LDD-series and the LDY-series are very similar, but there are some differences between them. The comparison is given in the table below:
| Parameter | LDY-series | LDD-series |
|---|---|---|
| General comparison | [+] Newer, more technological product | [–] Older, less technological product |
| End of life | [=] No | [=] No |
| Price | [+] Slightly more expensive | [–] Slightly cheaper |
| Regulations | [+] Medical-grade product from the box | [–] General-purpose diode driver. Compliance to medical standards is available on request |
| Rise time | [+] Faster | [–] Slower |
| Modifications | [–] Only a few standard models are available. Compact low-power versions are unavailable | [+] Many standard models are available. Compact low-power versions are available |

Other:
- XXXX means max. output power, both pulsed and CW (Pmax, in watts)
- YYYY means max. output current (Imax)
- ZZZZ means max. output voltage (Vmax)
- We recommend to pick Imax and Vmax values as close as possible to your diode’s operating сurrent and voltage in order to utilize completely the output power of the device and to ensure it’s optimal performance.
- The product of YYYY and ZZZZ shouldn’t exceed XXXX.
