Note:
①. In the above table, the typical values of test data are obtained according to the test system of CivilLaser.
②. according to the single-tube chip test data. When testing a single-tube chip, it is packaged in COS (Chip On Submount), and the COS test temperature is 25°C.
③. The chip should not be used when the use conditions exceed the limit value; at the same time, except for the typical value, other use conditions do not mean that the service life of the chip can be guaranteed.
④. covering 95% of the energy.
⑤. FWHM (Full width half maximum).
