The Stradus 488-150 from Frankfurt Laser Company is a Blue Diode Laser Module that operates at a wavelength of 488 nm. It delivers an output power of 150 mW with a power stability of less than 0.5 % and has a wavelength accuracy of ± 5 nm. This laser produces a beam of diameter 1.2 mm and has a small beam diameter of 0.8 mm. It has a beam circularity above 90% and beam alignment of up to 5 mrad. This vertically polarized laser has a TEM00 beam spatial mode with a beam quality factor (M2) of less than 1.25 and polarization extinction ratio of greater than 100:1. It has a beam divergence of 0.6 mrad & 1 m rad (small beam) and polarization orientation of ± 2°. This laser has a maximum beam centration of 0.5 mm and beam pointing stability of 5 µrad/°C.
The Stradus 488-150 has an RMS noise of up to 0.15 % (at 10 Hz - 10 MHz) and a full-off infinite modulation depth. It has a digital modulation of 200 MHz with a rise time below 2 ns and an analog modulation of 500 kHz with a rise time of less than 0.7 µs. This Class IIIb laser has class 4 ESD protection and is EU & RoHS compliant. It can be controlled via mini-USB and RS-232 interfaces with GUI. This laser requires a DC supply voltage of 12 V (laser head), an AC supply voltage of 90 V - 250 V (control box), and consumes a current below 1.5 A. It is available in a sealed optical cavity that measures 100 mm x 45.11 mm x 40 mm and is ideal for medical, biomedical, and industrial applications.
