Are laser diodes wavelength adjustable
The wavelength of a laser diode can be successfully controlled by using back-reflection, temperature stability and control, and a piezoelectric disk. Precise wavelength control is one of the most critical and most underappreciated challenges in laser diode and laser applications. Whether you are pumping a Yb-doped fiber laser, driving a solid-state crystal, performing Raman spectroscopy or locking an atomic transition line like Rubidium at. A tunable laser (alternative spelling: tuneable laser) is a laser for which the emission wavelength can be tuned (i. adjusted) (→ wavelength tuning). That tuning is usually possible during operation, i. Very.
