Absolute Maximum RatingsAbsolute maximum ratings are levels that can not be exceeded even momentarilyunder any external conditions. The levels are stipulated in terms of case temperature Tc=25 light output power (Po)This is maximum allowable output during continuousoperation.

The level is stipulated separatelyfor a Laser diode and a Ambient operating temperature (Topr)This is the maximum ambient temperature in which the element can level is defined by case temperature of the Ambient storage temperature (Tstg)This is the maximum ambient temperature for element 2. Electric Optical Characteristicsz Threshold current (Ith)Although P-IF curve distinguishes the LED light emittingregion A from the Laser oscillating region B, the currentlevel that triggers Laser oscillating is the threshold actuality, Ith is defined as the point where the straightline in B intersects the X Rated light output power (Po)This is recommended light output power during continu-ous Operating current (Iop)This is a current in the forward direction that is required togenerate rated light output Monitor current (Im)

The amount is given by the angle of the straightlight output power line with respect to forward current inthe Laser oscillating Lasing wavelength (Lp)This is peak lasing wavelength at rated light outputpower. The lasing spectrum is broadly classified as eithera single mode or a multi-mode as shown in the figure onthe right, and peak lasing wavelength is defined by themaximum spectral intensity in either Beam divergence angle : Parallel (Qh), Perpendicular (Qv) light radiating from Laser chip diverges as shown in the figure on the lower left.

10 Absolute Maximum RatingsDo not exceed, even momentarily, the maximum Laser diode is driven in excess of the maximum ratings, it causes not only instant breakdown ordeterioration but also considerable reduction in reliability. (1) Laser diode may be damaged by surge current generated at power on-off operation. Check on the transient characteristics of power supply to make sure that such surge current does not exceed the maximum ratings. (2) The maximum ratings are specified by case temperature at 25 C. Design should be made well to work with temperature. As temperature goes up, power dissipation as well as maximum light output power is 2.
