Equipment about optical stretcher
1. Single-mode ber (HI1060, Corning)
HI1060 single-mode ber with a diameter of 125 µm.
2. 980 nm pump laser (VENUS-980-M, Shanghai Haoyu)
A pump laser with a wavelength of 980 nm is used, as shown in Figure 3.8(a), and the
power adjustment range is from 0–850 mW. e 980-nm laser wavelength is in the
near-infrared wavelength region, and the absorption rate of the light source in water
is relatively low, so the damage to cells is negligible.

pler.
1. 980-nm optical coupler (VENUS-980-M, Shanghai Haoyu)
As shown in Figure 3.8(b), the optocoupler splits the laser from the laser into two
beams, with a split ratio of 50/50, and the two beams are connected to two sin-
gle-mode bers.
2. Optical isolator (OI-980, Shanghai Haoyu)
e optical isolator is used to prevent laser propagating from one of the opposite
bers from returning into the laser through another optical ber to damage the laser.
e optical isolator, as shown in Figure 3.9(a), is connected between the output of
