Description
The compact 532 nm module is a DPSS laser featuring high output power, very good beam quality and superior long-term power stability. The lower-coherence version features several longitudinal modes at higher power and typically single-longitudinal mode at a power level of ~10 mW. 532 nm wavelength radiation is commonly used in fluorescence excitation, scanning microscopy and general green light illumination. The free-space version features small beam diameter, very small form factor and wide operational temperature range from 15 deg. to 45 deg. C.

1 The optical power can be tuned from virtually 0% to 100%. However, other specifications, such as central wavelength, power stability, noise, polarization ratio, beam shape, quality and circularity 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 The long term power test is carried out at constant laser body temperature (+/-0.1 ‎°C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.
3 The long term power test is carried out at constant laser body temperature (+/-0.1 ‎°C) using an optical power meter with an input bandwidth of 10 Hz. The 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 Break-out-boxes AM-C8 and AM-H10 can be used for conversion of UART communication to either USB or RS232.
7 Slow TTL modulation can be enabled on request.
8 Excluding control interface pins and an output window/fiber assembly.
9 Whichever occurs first. The laser has an integrated operational hours counter.
