1. Emission bandwidth for 90% integrated power.
2. Typical values at 25°C and 0.6 NA collection optics.
3. Features common to all 5400 series diode lasers include:
a. Duty factor of 100%.
b. Temperature coefficient of wavelength is approximately 0.3 nm/°C.
c. Temperature coefficient of threshold current can be modeled as:
ITH2 = ITH1 exp [(T2 – T1)/T0] where T0 is a device constant of about 110°K.
