The CMC-940-4000-2 from Sheaumann Laser is a Continuous Wave Laser Diode that operates at a wavelength of 940 nm. It delivers an output power of 4 W and has a slope efficiency of 1 W/A. This multi-mode laser diode has a beam divergence of 30 degrees (vertical far-field) & 8 degrees (horizontal far-field) at FWHM. It requires a threshold current of 500 mA and DC voltage of 1.7 V. This laser diode consumes 4.5 A of current and dissipates 4 W of power. It has a 200 µm emitter and an optional microlens. This laser diode is available in a Cu submount package with ultra-low & high AR coating options and is ideal for defense, laser pumping, laser therapy, medical, and Raman spectroscopy applications.
