CASCADES™ ACTIVELY COOLED DIODE LASER BARS (NON VISIBLE)

Product catalog summary

Overview: nLIGHT's CascadesTM are high-power, actively water-cooled semiconductor laser bars designed for applications requiring high power, brightness, and reliability. These devices are based on a proprietary MOCVD structure and offer low beam divergence and narrow spectral bandwidth.

Specifications: The CascadesTM laser bars are available in wavelengths ranging from 780 nm to 980 nm and 1400 nm to 1600 nm. They feature a center wavelength tolerance of ±3 nm (±5 nm for 1400-1600 nm range), CW output power per bar ranging from 25 W to 100 W, and a bar length of 1 cm. The number of emitters per bar varies from 19 to 64, with emitter sizes of 100 µm or 120 µm and spacing from 150 µm to 500 µm. Spectral width (FWHM) is less than 3 nm to 10 nm, with slope efficiency greater than 0.4 W/A to 1.1 W/A.

Electrical and Mechanical Characteristics: Power conversion efficiency ranges from 30% to 55%, with threshold currents between 8 A and 26 A. Operating currents range from 60 A to 110 A, and operating voltages per bar are between 1.2 V and 1.85 V. The series resistance per bar is consistently 0.005 Ω. Storage temperature ranges from 10°C to 40°C, and operating temperatures are between 20°C and 35°C.

Thermal Management: Thermal resistance is 0.35°C/W, with a fluid flow rate of 200-250 ml/min/plate. Maximum inlet pressure is 55 psi, with an inlet to outlet pressure drop of 35 psi. Deionized water resistivity should be between 0.15 MΩ-cm and 0.3 MΩ-cm, and filters should be less than 20 µm.

Compliance and Warranty: These components do not comply with federal regulation Title 21 CFR, Chapter 1, Subchapter J. Purchasers must ensure compliance before selling to end-users. nLIGHT offers a limited warranty and may change specifications without notice.
