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:
I
TH2

] where T
0
is a device constant of about 110 °K.
d. Temperature coefficient of operating current is approximately 0.5 to
0.7% per °C.
4. Forward voltage is typically: V

5. Wavelength ranges for the 5420 series:
800-820 nm
810-850 nm
842-862 nm
Wavelength range for the 5430 series is limited to 820-840 nm.
A variety of part numbers are available that each designate a particular subset within these wavelength ranges. Consult tables on page 5.
6. Astigmatism is less than 5 µm.
