Description
405 nm diode lasers are popular in a variety of fluorescence applications. Many organic materials have strong fluorescence at this excitation wavelength. Other applications include UV curing and inspection. 405 nm radiation became particularly popular due to the fact these diodes are used in Blu-ray optical disc equipment thus, they are inexpensive.
Integrated precision driver electronics ensures low-noise and very stable operation throughout the wide temperature range. Internal voltage up-conversion allows using a 5V power supply while maintaining low noise operation.

1 The optical power can be tuned from virtually 0% to 100%. However, other specifications, such as central wavelength, power stability, noise, polarization ratio are not guaranteed at power levels other than factory preset power. Significantly worse power stability is to be expected at very low power levels, e.g. <3% from specified nominal power.
2 Long term power test is carried out using an optical power meter with an input bandwidth of 10 Hz. Actual measurement rate has a period of about 20 seconds to 1 minute.
3 Long term power test is carried out using an optical power meter with an input bandwidth of 10 Hz. Actual measurement rate has a period of about 20 seconds to 1 minute.
4 Noise level is measured with a fast photodiode connected to an oscilloscope. The overall system bandwidth is from 2 kHz to 20 MHz.
5 For lasers without integrated optical isolators.
6 TTL digital modulation up to 10 MHz.
7 Excluding control interface pins and an output window/fiber assembly.
8 Whichever occurs first. The laser has an integrated operational hours counter.
