Buying Direct Diode Lasers
Direct diode lasers (DDL) use the output of laser diodes directly for applications such as laser material processing. Compared to diode-pumped solid-state lasers, they offer advantages in cost and power conversion efficiency. Their limitations in beam quality and pulse intensity are more and more shifted by further technological progress.

![]() A Tradition of High Power Photonics Leadership QPC Lasers Inc.15632 Roxford Street Sylmar, CA 91342 United States | ![]() QPC Lasers full vertical integration from epitaxy through packaging allows us to offer standard and custom diode solutions in packages ranging from open heat-sink mounts to complete OEM light engines that provide performance without compromise. |
![]() Rue François Mitterrand Institut d'Optique d'Aquitaine 33400 Talence France | ![]() SHIPS TODAY: AeroDIODE offers fiber-coupled laser diodes with very high brightness (meaning high power and high precision when focusing) dedicated to micromachining applications between 808 nm and 1550 nm as stock items or associated with a high power laser diode driver with air cooling. Most turn-key diode & driver solutions are optimized for single-shot to CW performances. Many multimode versions are available with CW emission up to 450 W in a 200-µm core multimode fiber or up to 250 W in a 135-µm core fiber or 160 W in a 105-µm core fiber. The highest brightness/power models are based on special laser diodes for emission at 808 nm, 915 nm, 940 nm, 980 nm or 1064 nm. See also our tutorial on fiber-coupled laser diodes. |
![]() Arzbergerstr. 10 82211 Herrsching Germany | ![]() Hamamatsu Photonics DDL is a laser heating light source that efficiency transmits and focuses laser from the LD stack module and directly irradiates the materials. Since DDL dose not use optical fiber, it is an energy-saving light source with little transmission loss due to complicated optical systems. DDL can be used for a variety of applications including for heat processing such as welding, hardening and cladding as well as pumping of solid-state lasers. |
![]() 30 Years of Laser Excellence MonocromC/ Vilanoveta 6 08800 Vilanova i la Geltrú (Barcelona) Spain | ![]() Monocrom has developed direct diode lasers for industrial applications. They are based on our solder-free laser bar Clamping™ technique, which lets them be efficiently cooled and reach a long lifetime. Up to 8 kW continuous-wave output power is possible. |
