515 NM LASER (CW, DIODE; PM FIBER)
描述
Green laser sources are often used for fluorescence excitation, Raman scattering, as well as for Ti:sapphire pumping applications. High long-term power stability is ensured by TEC thermal stabilization, thermal and optical feedback. USB communication lets laser be easily controlled by connecting it to computer in any laboratory. This laser module is permanently fibered coupled to a single-mode polarization-maintaining fiber and provides a perfect beam with a polarization extinction ratio of more than 20 dB.

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 TTL digital modulation up to 10 MHz.
6 Excluding control interface pins and an output window/fiber assembly.
7 Whichever occurs first. The laser has an integrated operational hours counter.
