The JOLD–Stacks Series offers a highly modular approach for power scaling well into the kW range. The series features compact, lightweight, and robust multimode, free-space laser diode stacks with options for 760-1070 nm, CW & QCW operation, output power up to 2400 W (QCW), no lensing or FAC or FAC/SAC collimation, active or passive cooling, and are completely customizable. JOLD-Stacks achieve optimal beam quality by reducing the stack pitch without compromising cooling capacity, and our proven hard-solder technology and strictly monitored production processes ensure tried & tested reliability in the harshest environments.

Many configuration options available:
- Wavelength: Options from 760-1070 nm (multi-wavelength stacks available for “color mixing”)
- Optical output power: number of bars per stack
- Operating mode: CW or QCW/long-pulse
- Cooling: active with DI or tap water or passive/conductive
- Packaging: with or without housing and protective window option
- Lensing: FAC or FAC/SAC lensing available
Passively Cooled Stacks:
QCW- and long-pulse configurations utilize vertical stacks made up of CTE-matched submounts on Direct-Copper-Bonded (DCB) substrates. This type of vertical stack clearly offers several advantages:
- Tap water or passive cooling of the DCB
- Light-weight
- Small footprint
- Compact multi-stack arrangements offering additional power scaling (multi-stack packages)
- Ideal for Medical applications like laser-based therapy for ophthalmology, dermatology, and esthetics

Actively Cooled Stacks:
Microchannel-cooled packages (MCCP) which are actively cooled with DI water for CW-operation, utilizing best-known practices regarding microchannel designs, DI-water specification, and cooling circuit maintenance, enabling package-limited lifetimes > 10k hours – relevant for industrial applications:
- DI-water cooling for MCC packages
- Light-weight
- Small footprint
- Compact multi-stack arrangements offering additional power scaling (multi-stack packages)
- Ideal for Material Processing & DDL applications like welding, soldering, hardening, and annealing
