What is the spectrum line width of the listed DPSS lasers?
A8: Depending on model, mostly lies in the range of 0.1 – 0.2 nm (1-2 A) Q9. How is the output power stability of listed DPSS laser modules versus temperature fluctuation? A9: Output power stability of most diode laser modules/systems and DPSS laser modules with optical feedback control remain reasonably unchanged. Output power stability vs. temperature fluctuation of most DPSS green laser modules without optical feedback control is shown in figure. Typical output power stability vs. change of temperature in the range of (10 through 40 °C) change of most DPSS laser systems does not exceed 1% and is shown in figure. Change in output power vs. change in temperature of blue laser modules without optical feedback control is similar to figure. Each laser has an optimum temperature that (in the 20 to 35 °C range) the laser produces its maximum output power. This optimum temperature is determined for each laser and is indicated in the laser’s specification and instruction manual. The further
